I came back from Germany in February 1964 and saw them on 'The Hootenanny Show' on BBC Television - As I recall , it was Barnie , Cairan , Luke and Barney .No Mister Sheehan then , so from my viewpoint that is the original line up . And the 'Best Mix' with John in the Line Up was on the Revolution album , with Ronnie singing in Spanish as well .
