Stars have turned on Ed Sheeran in the escalating row over the new Band Aid single - with Spandau Ballets Tony Hadley telling him to shut up.
Trevor Horn, producer of a fresh 40th anniversary version of Do They Know Its Christmas?, has also been critical of Sheeran after the singer spoke out against the new version of the charity track.
Sheeran revealed last week he would have preferred his vocal contributions from a 2014 recording were not used on the new version.
The songs co-writer Bob Geldof has been defending the song against criticism that it fuels pity rather than partnership while promoting harmful stereotypes about Africa.
And fellow acts have now been hitting back at Sheeran for his stance, including Hadley who was among those who took part on the original 1984 recording.
Meanwhile, listeners hearing the new version for the first time on BBC radio yesterday have been giving their thoughts - with opinions ranging from a hot mess and horrific to better than I thought it would be and iconic.
A devastating famine in Ethiopia inspired Geldof to launch Band Aid in 1984, writing Do They Know Its Christmas? alongside Ultravox frontman Ure and then organise the fundraising Live Aid concerts staged in July 1985.
Sheeran revealed last week his unhappiness about his vocals being used in the new rerecording which is being officially released this Friday.

Trevor Horn, producer of the original 1984 single as well as the new 40th anniversary rerecording, has said he would gladly have left off Sheerans vocals from 2014
The 40th anniversary Ultimate Mix was given its first radio airplay on Monday
He said he would have respectfully declined permission for re-use of his contribution to the 30th anniversary production from 2014 - while other critics in the past have included Lily Allen and Damon Albarn.
Sheeran revealed how his concerns about the song followed points made by his friend Fuse ODG, a London-born Ghanaian-English rapper.
Fuse ODG - real name Nana Richard Abiona - spoke out last week, as he released a response called We Know Its Christmas and urged the BBC not to promote the song.
Sheeran, 33, originally featured on the 2014 version of the track alongside the likes of Sting and Harry Styles which aimed to raise money for the Ebola relief efforts.
Taking to his Instagram stories on Sunday last week, Sheeran posted: My approval wasnt sought on this new Band Aid 40 release and had I had the choice I would have respectfully declined the use of my vocals.
A decade on and my understanding of the narrative associated with this has changed, eloquently explained by @fuseodg. This is just my personal stance, Im hoping its a forward-looking one. Love to all x.
Fuse ODG himself rejected an offer to take part in the 2014 version of Do They Know Its Christmas? on which Sheeran featured.
The rapper wrote on his Facebook page last week: Ten years ago today, I said NO to Bob Geldofs Band Aid - Do They Know Its Christmas project due to the fact its a campaign that dehumanises Africans and destroys our pride and identity in the name of "charity".
The original 1984 recording of Do They Know Its Christmas? featured stars include Paul Young, Bono, Sting, George Michael, Bananarama and Spandau Ballet

But there has now been a backlash against Sheerans remarks, with Hadley - who featured on the original 1984 version of Do They Know Its Christmas? - saying critics of the track ought to keep quiet.
Hadley told Radio 2s Radio 2s The Jeremy Vine Show: I think they should shut up, to be honest.
We were there. I mean, if you take that route, then nobody does anything to help anybody. Its just nonsense.
I mean, you know, do we get rid of Children In Need? Because you say, well, the government should supply all the funds for everything.
You know, everybodys trying to do their bit to support various charities, and we were doing our bit innocently to support what was happening in Ethiopia and in Africa, and its still going on.
Thats the other thing - its still going on, so do we sit back and we do nothing? So, Im sorry, but I dont think so.
Meanwhile, Horn said that after hearing of Sheerans latest thoughts he could have gladly not used him on the new version.
This new mix combines the recordings done in 1984, 2004 and 2014 - meaning a young Sting sing alongside a young Ed Sheeran, a young Boy George with a young Sam Smith, a young George Michael beside a young Harry Styles.

The young Bono features with an older Bono, Chris Martin with Guy Garvey, the Sugababes and Bananarama, Seal and Sinead OConnor, Rita Ora and Robbie Williams, Kool and the Gang and Underworld.
Other stars featuring include Paul McCartney, Sting, John Taylor, Phil Collins, Roger Taylor, Paul Weller, Damon Albarn, Midge Ure, Johnny Greenwood, Gary Kemp and Justin Hawkins.
Horn, who also produced the 1984 original, has now said of the song: I think it was done with the best intentions, and so I think its not a good idea to misinterpret it as some, some kind of patronising thing.
It was done to help. And really it was extraordinary that the music business could achieve that much. I dont think anyone ever anticipated that it would bring get that kind of money together.
In response to Sheerans criticisms, he added: Im sorry Ed Sheeran is not happy. If Id have known, I would have gladly not used him.
Gig promoter Harvey Goldsmith, who was behind the 1985 Live Aid concert,said: Yeah, exactly. Stuff him.
Goldsmith told of writing cheques worth £3million in the past seven months from cash raised by the Band Aid Trust to support school and medical projects.
He told the Jeremy Vine programme: The charities dont have a problem whatsoever coming to us to ask for grants every single day of the week, so they dont have a problem.

I dont know what Ed Sheerans problem is, nor this other chap who Ive never actually heard of personally.
But anyway, I dont know what his problem is, but nevertheless, there is famine raging, and this is partly because of the climate change issues, because theres been theres either no rain whatsoever and its baking dry, or theres so much rain that the earth cant soak it up.
And thats whats going on, and we need to be mindful of that - and yeah, if we can help, well help. And if they dont like it, were very happy to look elsewhere.
But the songs co-writer Ure appeared more conciliatory, saying: Its rather unfortunate we didnt run it past Ed.
Hes a lovely guy - and it should have been permission asked him, requested for but when all the artists commit to recording any of the Band Aid tracks, versions that have been out there, they are actually giving their permission for it.
Meanwhile, Geldof became emotional when he appeared as a guest on Zoe Balls Radio 2 breakfast show on Monday for the first public broadcast of Do They Know Its Christmas? 2024 Ultimate Mix, marking 40 years since the original release.
Sounding choked up, he told the presenter: I think its a work of art. Arent the voices incredible?
I think its one of the greatest production art that has ever been done on a rock and roll record. Genuinely.
The 20th anniversary version recorded at Air Studios in Hampstead, north London, in November 2004 included acts such as Ms Dynamite, Natasha Bedingfield and Keane
Harry Styles featured on Band Aids 2014 re-recording, alongside his One Direction bandmates
The song was originally created by Sir Bob Geldof and Midge Ure in a bid to raise funds for anti-famine efforts in Ethiopia, and went onto top the charts and raise millions
Ball called the track an extraordinary record, adding: Weve both had a cry and its that thing, theres so many people involved in that, that perhaps arent with us anymore, and this time of year, we think of those.
Geldof had earlier responded to criticism of Do They Know Its Christmas? in an interview with the Sunday Times at the weekend.
He said: This little pop song has kept millions of people alive. Why would Band Aid scrap feeding thousands of children dependent on us for a meal?
There are 600million hungry people in the world - 300 million are in Africa. We wish it were other but it is not. We can help some of them. Thats what we will continue to do.
