At the age of seventeen, Harris was recruited by New Model Army to replace original bass player Stuart Morrow (1980–85) who had left the band midway through the 1985 'No Rest for the Wicked' tour.
[1] He toured extensively with the band over the next five years, playing at venues across Europe, the United States and Japan.
He also contributed to New Model Army's milestone albums, The Ghost of Cain (1986) and Thunder and Consolation (1989), before leaving in 1990, when he was replaced by Peter "Nelson" Nice.
When the band reformed in 1996, he was replaced by former The Damned and Eddie and the Hot Rods bassist, Paul Gray.
[5] When Pants split, Harris and Oliver collaborated on the self-described "retro-futurist synth rock" duo The Pieshop Boys, appearing sporadically between 2008 and 2013.
