[5] The song was conceived as a backing track originally given to Michael by his frequent collaborator James Jackman in 2012.

[6] According to Jackman, "George phoned me one evening, really excited and said, 'I've got the most amazing hook over your track.'

Paul Feig was set to direct, with Emma Thompson and Greg Wise co-writing the screenplay.

[7] In October, it was announced that Thompson would star as well, and that the film would feature the music of Michael (who died in 2016), including "Last Christmas", and previously unreleased tracks.

[8] Feig told in an interview to BBC News that Michael was about to compile his new album before his death.
