This old chesnut was revived by Flatt & Scruggs in the late 50s, and it was a great choice. Everyone loves it, particularly the kids. It’s a jam favorite because it has only two chords but also an easily learned bit of weirdness at the end of the verse/chorus (“Yes, sir” has an unexpected extra measure).
We’ve played this for eight years now, and it has evolved. I especially like the swingy feel Chris now gets on his guitar breaks.
