Well after a long search my hunch was right all along. Cal Danger is not Tony Dangerfield & they are not related although they did tour together in the early 60's. Cal Danger is in fact real name Gorden Patterson & this is the band line up at the time of this recording. Cal Danger & The "Blue Caps" (Late 1961) Gordon Patterson (Lead Vocals) "Cal Danger" Jefferey Beck (Lead Guitar) "Jeff Beck" John Owen (Rhythm Guitar) George Clarke (Bass) Mick Godfrey (Drums) so this is now completly solved & thanks to Alan Hope aka Kerry Rapid singer & musician with Screaming Lord Sutch in the early 60s for confirming this.I must point out that Cal Danger was an absolute Gene Vincent fan / impersonater right down to the leather & limp.
