The Number One Song in Heaven

Moroder produced and co-wrote the song, which closes No. 1 in Heaven. Released as a single in 1979, it became the duo's first hit since Looks, Looks, Looks in 1975, reaching number 14 in the UK and number five in Ireland. The 7 inch ran 3:48 with a 6:56 long version on the flip, the 12 inch ran 4:02 and 7:27, and both were pressed in red, blue and green vinyl as well as black.

Pitchfork's Stuart Berman wrote that it poses the question that hangs over their whole career, whether they are being ironic, but concluded that its belief in disco's unifying power is entirely genuine. He described a slow-motion opening like a beam of biblical light, then a second act that feels like being rocketed into the stratosphere. Joy Division's Stephen Morris said that he and the band were into this song, and into Frank Sinatra's Greatest Hits, when they worked on Love Will Tear Us Apart.

Other versions

Sparks re-recorded the song in 1997 for Plagiarism, with vocals by Jimmy Somerville and orchestration by Tony Visconti. That version reached number 70 in the UK and made the top 30 of the Billboard dance chart. The CD singles added a radio edit, an extended version with Somerville, and remixes including a Tin Tin Out mix.
