Christopher James Harley, known by the stage name Chris Rainbow, was a Scottish pop rock singer and musician whose songs "Give Me What I Cry For" and "Solid State Brain" were often played by British radio DJs Kenny Everett and Tony Blackburn in the 1970s.

Kenny Everett was an English radio DJ and television entertainer. After spells on pirate radio and Radio Luxembourg in the mid-1960s, he was one of the first DJs to join BBC Radio's newly created BBC Radio 1 in 1967. It was here he developed his trademark voices and comical characters which he later adapted for television.
