"Jump Start My Heart" (1999)
“Jump Start My Heart” is a song that Bono was developing for The Million Dollar Hotel soundtrack, but the song was not used in the movie or on the accompanying soundtrack.
The European version of the DVD release of the film included a documentary titled One Dollar Diary. “Jump Start My Heart” features in the documentary, and we see Bono joined by Daniel Lanois sharing a microphone and singing the song. The music in the background is provided by The Million Dollar Hotel Band, and not U2 themselves. The song is a short two minute clip. The lyrics appear to be something that Bono and Lanois are developing on the spot, and it does not feel like a fully developed song.
No audio version of the track has ever been released.
