In a documentary on the making of
Invisible Touch,
Phil Collins revealed that the song originated from a
LinnDrum pattern he created.
Tony Banks added an ominous chord progression, establishing the song's dark tone and inspiring its lyrics, which depict a
drug addict’s struggle to contact their dealer for another fix. The lyrics explore themes of addiction ("a load on your back that you can't see," "shake it loose"), desperation ("I've got to get it to you," "I keep calling but you're never home"), and eventual anguish ("now I'm in too deep," "please get me out of here!") . Collins intensified the emotional climax with dramatic drum fills featuring his signature
gated reverb. The album version extends to nearly nine minutes, including a refrain and keyboard solo, which were cut from the single and radio edit. The song's working title was "Monkey, Zulu". ==Versions==
