Stray is an English hard rock band formed in 1966. Vocalist Steve Gadd (born 27 April 1952, Shepherd's Bush, London), guitarist Del Bromham (born Derek Roy Bromham, 25 November 1951, Acton, London), bass player Gary Giles (born Gary Stephen Giles, 23 February 1952, North Kensington, London) and drummer Steve Crutchley (born c 1952) formed the band whilst all were attending the Christopher Wren School in London. Richard "Ritchie" Cole (born 10 November 1951, Shepherd's Bush, London) replaced Crutchley in 1968. They signed to Transatlantic Records in January 1970.
The group's brand of melodic, hook-laden hard rock proved to be a popular draw on the local club scene during the early 1970s. However the band did not have commercial success with its record releases. At one stage Charlie Kray (brother of the Kray twins Ronnie and Reggie), was their manager. Gadd left the band in 1975 due to artistic differences and was replaced on vocals by Pete Dyer. The groups early musical style consisted of blues rock, acid rock and psychedelic rock. They then went on to join the hard rock and progressive rock movement.
Samantha Buck temporarily replaced Kathryn Erbe while she was on maternity leave. (Though Kathryn temporarily appeared in a few episodes until her return.) Buck appeared as G. Lynn Bishop from episode 5, "Pravda" through episode 11, "Mad Hops."
