In summer 1966, Gibson and Turnbull joined unsigned Newcastle band The Chosen Few, who had released two singles the previous year written by their then vocalist and guitarist Alan Hull, later of Lindisfarne.
The band then secured a deal with RCA Records in summer 1967 under manager Don Arden and went on to release three singles: "On Love" which made a minor chart appearance, "Happy Land" and "Man in Black" produced by Steve Marriott and Ronnie Lane.
Later, Gibson was re-united with fellow Griffin members Kirtley, Craddock and White and Bud Beadle, Steve Gregory & Geoff Condon, the horn section of the now-defunct Airforce in Simpson's Pure Oxygen.
