Derek Forbes (born 22 June 1956, Glasgow, Scotland) is a Scottish bassist, vocalist, and sometime guitarist, best known for his work with Simple Minds (with whom he joined forces in 1978, and began recording the early demos and forward into their 1979 debut album, Life in a Day until shortly after their 1985 hit, "Don't You (Forget About Me)").He was dismissed from the band, apparently due to petty jealousy, as cited by Jim Kerr, who stated that it was a regrettable mistake, prior to the release of the global success of Once Upon a Time.
