Jim Bob played in various bands during the late 1970s and early 1980s, one of which was Jamie Wednesday who were performing between 1984 and 1987. In 1987 Jamie Wednesday split up just before a gig at the London Astoria. Morrison and Les "Fruitbat" Carter filled in, playing along to a backing tape, and Carter USM was born. Jim Bob and Les Carter had known each other since the late 1970s, when their bands The Ballpoints (featuring Jim on vocals) and Dead Clergy (Les on bass and vocals) used to rehearse at the same studio behind Streatham station. When The Ballpoints' bassist quit at the end of 1980, Carter joined the band, who then went on to play several gigs under the name of Peter Pan's Playground.
