How 60's music impacts on so many of the baby boomer generation.
I have never heard of David Van Cortlandt Crosby.
Wiki tells me that he was an American singer, guitarist, and songwriter. In addition to his solo career, he was a founding member of both the Byrds and Crosby, Stills & Nash.
Crosby joined the Byrds in 1964. They had their first number-one hit in April 1965 with a cover of "Mr. Tambourine Man" by Bob Dylan.
Well there you go, David Crosby has popped his clogs and I had no idea of who he was.
