Written by Dolly Parton as a farewell song to Porter Wagoner upon her departure from Wagoner's TV show ... somewhere around the early 70's as I recall. She's recorded it several times since, once about ten years ago as a duet with Vince Gill ... that's her most recent recording of it, I think, on the album "Something Special", which was more or less a compilation of her favorite songs by herself and others. I've got it around here somewhere ... played it just the other day.
I'll skip my turn though; unfair advantage - I remember the liner notes from the album
Besides, I'm not a regular visitor to this thread ... dunno how I popped in (musta been a misclick on my part - I thought I was headed for a different thread

), and just thought it was really cool I had the current answer. Go ahead and do another, edgar.
