The reworking of the Hollies 1969 hit took the festive top spot to cap a memorable week for campaigners, friends and family of the 96 victims of the disaster during the FA Cup semi-final between Liverpool and Nottingham Forest on April 15, 1989.
A new police investigation into the victims’ deaths was announced by Home Secretary Theresa May, and the High Court quashed accidental death verdicts recorded by the original inquest into the tragedy. A new inquest will now be held.
Sir Paul McCartney, Robbie Williams, Mel C, Beverley Knight, Rebecca Ferguson, Paloma Faith and Frankie Goes to Hollywood singer Holly Johnson were among the artists who featured on the Justice Collective song.
Liverpool Walton Labour MP Steve Rotherham, who backed the Hillsborough campaign, said: "We have done in nine weeks what it normally takes nine months or more to achieve, working with a phenomenally dedicated team all of whom have worked for free."

The Government said last week it would waive VAT on the Justice Collective's charity single, after a campaign. It also announced it will fund legal representation at the new inquest for the families of those who died.
