Sefton Central Labour MP Bill Esterson is urging people to help send the Hillsborough Justice Collective single to number one for Christmas.
The single, He Ain't Heavy, He's My Brother, was released on Monday.
Artists on the track include Paul McCartney, Robbie Williams, Rebecca Ferguson and a host of other leading musicians.
Money raised will go to fund the ongoing legal campaign.
Bill Esterson is urging people to buy the single to raise much needed funds for the Hillsborough campaign and to send the single to number one for Christmas.
Bill said: "This is a great song and it is for a great cause, so of course I expect it to be the top of the charts for Christmas.
"Everyone should get behind this single to help the families and campaigners continue the fight for justice for the 96.
"I know people in Sefton Central will continue to show their support for the families and the campaign and I am confident that the single will be the Christmas number one."
Bill said: "The single is a great Christmas gift which I know will be at in lots of people's stockings on Christmas morning.
"But more importantly, this single will go a long way to helping the families get justice. It will raise money and awareness.
"I am confident that the new year will see great strides in the long campaign for justice and I will continue to do all I can to support the campaigners."
