A musician whose career dates back to the mid-1960s, Pyle was born in Luton in 1946 and reached his teenage years when rock & roll supplanted skiffle as the music of choice for British youth.
When Bunker and Abrahams left McGregor's Engine to form Jethro Tull with Ian Anderson on flute and vocals and Glenn Cornick on bass, Pyle continued to play with local bands.
Abrahams left Jethro Tull after the first album This Was, following a dispute with Anderson about the band's future, to form Blodwyn Pig with Pyle on bass, Jack Lancaster on saxophone and Ron Berg on drums.
After the Blodwyn Pig disbanded, Pyle joined Juicy Lucy (who includes Micky Moody who would play later with Whitesnake) and Savoy Brown, as well as sessions for Rod Stewart on his 1971 album, Every Picture Tells a Story.
He playeds on Lee's first solo album, Pump Iron with former King Crimson musicians, Boz Burrell on bass, Ian Wallace on drums, and Mel Collins on saxophone.
The same year, he participated in the concept album Peter and the Wolf by Jack Lancaster and Robin Lumley, with musicians of different horizons, Alvin Lee, Gary Moore and John Goodsall on guitar, Percy Jones and Dave Marquee at the bass, Brian Eno, Manfred Mann on synths, Bill Bruford and Phil Collins on drums, Stephane Grapelli on violin, etc.
He played on Mr. Big Man on the band's 1977 album Sleepwalker, the single only track "Father Christmas" and 1978's Misfits, where he only appeared on six of the ten songs, before leaving with keyboardist John Gosling.
