The very first album I ever got was Johnny Cash Live at San Quentin. My Aunt Olga got it for me as a birthday present, much against my mother's wishes because it contained that vulgar song, "A Boy Named Sue."
Cash did not write that song. It's the product of Shel Silverstein. The song came to the attention of Cash when Shel performed it at one of Cash's house parties in February 1969.
That must have been a helluva party. Dylan was there, trying out a new song called "Lay Lady Lay." Kris Kristofferson had just written something he called "Me and Bobby McGee." A Canadian named Joni Mitchell strummed away at "Both Sides Now." And there was Silverstein with his song.
