Clem Clempson

David "Clem" Clempson (born 5 September 1949) is an English rock guitarist who has played as a member in a number of bands including Colosseum and Humble Pie.
Clempson began his career in the late 1960s with the power trio, Bakerloo (originally The Bakerloo Blues Line), playing blues-rock. In 1969, he joined Colosseum, until they disbanded in 1971. After Colosseum's split he went on to join Humble Pie in 1971, replacing Peter Frampton. When the band split in 1975 he and Greg Ridley joined drummer Cozy Powell to form Strange Brew. During this period, Clempson auditioned for Deep Purple but lost to Tommy Bolin. Although he played in Marriott's All Stars, he opted in 1980 not to join the reformed Humble Pie, choosing instead Jack Bruce & Friends.
In 1977, Clempson formed the short lived band Rough Diamond with former Uriah Heep singer David Byron.
