A stream of successful UK musicians arrived at a recording studio in the shadow of London's Grenfell Tower on Tuesday to add their star quality to a charity single.
Chart-toppers Jesse J, Robbie Williams and Louis Tomlinson were among those seen at the Sarm music studios.
"It's heavy, I think everyone in here feels the same way. It's a heavy time and the only thing that can make change is to not be afraid and to come together and to, just, love deeper. And use our voices and our talent to spread the music," Jessie J said.
Organiser Simon Cowell said he hoped the single, a cover of Simon and Garfunkel's hit 'Bridge Over Troubled Water', will raise money for those affected by the disaster.
"It's been - and I am not just saying this - an absolute team effort. Everyone chipped in, every record label, all the artists. It's been incredible."
After hearing the single for the first time - although still a work in progress - Cowell said it was beautiful and gave him "chills".
