OK, NONE of the sheet music that has turned up matches the tune in my head to the Bob Wills/Tommy Duncan lyrics. Which MIGHT be a two-step, but is NOT a Fandango. Unfortunately, I can't do abc etc. from what I hear in my head, but we are definitely looking at two completely different songs here, and Louie, did the one you learned in 1930 have words, or was it just a tune with a lot of arpeggios and riffs?
