As I’ve said before, I didn’t greatly care for Donovan, though he did give me a big laugh when he claimed in his autobiography to have been a major influence on the Beatles, Dylan and just about every name on the 60s folk scene.
His composition Colours was released in May 1965 in the UK, where it reached No 4, and the following month in the US, where it got to No 61.
A different mix without harmonica (a great improvement) was included on his October 1965 album Fairytale.
He re-recorded it in 1968 for the 1969 album Donovan’s Greatest Hits, produced by Mickie Most. It’s not far off a parody, with a ghastly vocal backing and someone kicking a football around the studio.
