As an oddity and an aside, there is a very strange, and distinctly plaintive, version of Man of Constant Sorrow on the first Ginger Baker's Air Force album (c. 1970, just after the demise of Blind Faith) with Denny Laine (later of Wings fame) on lead vocals. In his version, Laine it is to Birmingham that Laine bids his farewells... and it is the live audience at the Royal Albert Hall which finds itself on the receiving end of most of the grief and sorrow, which, though intense, is mercifully finite.
