Originally written by the Canadian pop punk band Simple Plan, "If I Die Tomorrow" was left off their 2004 album Still Not Getting Any... as the band did not feel that it fit in with the rest of the album. After finishing work with Simple Plan, producer Bob Rock brought the song to Mötley Crüe knowing that they were looking to record new material to include on their new compilation album. After hearing the song, Mötley Crüe bassist Nikki Sixx made several lyrical and music changes to it before the band recorded it.
A video was made to promote the single, which featured each one of the band members, which includes Sixx, vocalist Vince Neil, drummer Tommy Lee and guitarist Mick Mars each individually in a nightmarish scene from their past. Sixx's scene shows him overdosing on heroin; Neil killing his friend, Razzle from Hanoi Rocks; Mars in a hospital bed, battling Ankylosing spondylitis; and Lee, in prison. Also starred actress April Scott.
