A strange release for the fact that Bono and The Edge feature on it, but was never really advertised back in 1990. The story goes, when Max Q (Michael Hutchence/Ollie Olson) were jamming, The Edge and Bono dropped by the sessions after a Melbourne U2 show back in 1989 and recorded their parts of the song, which were recorded by Michael and Ollie. They only appear on the "New York, New York" track.
There was also a video produced for the single which features a cameo by Bono.
