I had to wing this one last Friday night, and it wasn't all that comfortable. Can anyone suggest reasonably accurate changes in G? Following the bass line, it's something like G7 - Bb7 - A7 -Ab7. I'm missing the chords for the last line of each verse. I think the chorus is basically a repeated G7 to C7, but I'm not sure about the "never heard such scufflin' and shufflin' till the break of dawn" part. Does anyone out there perform this song?
