"One Too Many Mornings" found fame in 2001 after appearing on several chillout compilation albums.^{[citation needed]} The version of "Chemical Beats" is the full-length version, with an extended intro. The full version of the song wasn't included on Exit Planet Dust due to an uncleared vocal sample and has not been available since. The sample was "take this, brother, may it serve you well," from the Beatles' song "Revolution 9".^{[citation needed]}
