Pete Holdsworth was the singer for London Underground. He was cofounder of the [[label:On-U Sound]] label in 1980. As London Underground dispanded in 1984 he slipped out of the limelight but not from the scene.

In 1989 he formed another short-lived band called Mystery Train, which featured reggae writer David Katz on keyboards.

Pete re-emerged fully in around 1994 as the label manager for the now successful [[label:Pressure Sounds]] reggae re-issue label - initially as a subsiduary of On-U Sound. He was also involved in the setting up of the [[label:Green Tea]] label in 1997.
