My favorite country duet from the '70s...

at The Roadhouse, Sirius Ch. 62: "There ain't no good in an evil-hearted woman, and I ain't cut out to be no Jesse James...and you don't go writin' hot checks, down in Mississippi, and there ain't no good chain gang..."
That Johnny Cash-Waylon Jennings duet from 1978 has always been one of my absolute favorite songs, period, one that I don't hear much anymore, and another one of those songs they could play ten times a day and I'd never tire of it...of all the duets the stars of the day recorded back then, that one was the best, I think.
