After leaving John's Children in 1967, Marc Bolan forms the acoustic duo Tyrannosaurus Rex with percussionist Steve Peregrin Took. The duo signs a recording deal with producer Tony Visconti, for release on EMI's [l=Regal Zonophone] label. Following a poorly received US tour, Steve Took leaves to work on his own music and is replaced by [a=Mickey Finn (3)].
After a while Tony Visconti shifts label outlet for his productions from Regal Zonophone to [l=Fly Records (3)] in UK. After much urging from his producer, Marc Bolan abbreviates his group name to T. Rex and expands to a quartet with the addition of Steve Currie on bass and Bill Legend on drums.
