THE BALLAD OF MOMMA ROSA PARKS, sung by The Baytown Singers, appeared on the various-artists album "This Land Is Your Land: Songs of Social Justice," 1964. The most complete description of the album I can find is at this Judy Collins discography. It says the album was published by UAW (United Auto Workers?).

Nick Venet's real name was Nikolas Venetoulis. He produced albums for many artists and also worked as an actor.
