There was a certain influence of Young Tradition on SA -- Royston Wood replaced Jim Boyes at some point in the group's history, while Dave, for all the difference in accent, had a timbre to his voice not a million miles from the quasi-falsetto Bellamy 'bleat'.
I once played Peter Bellamy, staying over with us after a Cambridge gig, the opening track of their first Trailer record, Last Valentine's Day. "I don't remember us recording that track." was Pete's response.
