 He joined T. Rex (recently renamed from Tyrannosaurus Rex) as bass guitarist in November 1970 (although the band were still listed as a duo) and continued to play with them until late 1976.He appeared on all of Marc Bolan's hit singles from "Hot Love" (1971) to "Laser Love" (1976), as well as the albums "Electric Warrior" (1971) to "Dandy in the Underworld" (1977).His innovative and, for the time, sophisticated bass playing can be seen to good effect in the movie "Born to Boogie".
