May have mentioned this on a thread some time ago, but in the 50s, I heard several 78 sides by Gene Autry that were, uh, bawdy, I guess. They were sold from under the counter at the local record stores. The only one I recall by name was "Pistol Packin' Papa," a parody of "Pistol Packin' Mama," a Western hit at the time they were released. By today's standards, they were pretty mild.
