I first heard that song this summer. My husband bought an old record player and some records from The Salvation Army and we spent hours relaxing in the garage listening to them. The title sounds very provocative, but it’s really a great song, we laughed all the way through it because it was just so different. I think it was on an Outlaws record, I’d have to check.
It isn’t on the Outlaws album, this best of album has all of my Jerry Jeff Walker favorites, and that is Merle Haggard that is referenced to in that song.
