I'm looking for a bluegrass version to listen to, but my general impression is that the non-jazz chords to this song can go either like "Plastic Jesus":

|| CC/FF/GG/CC||
From a version that I have by Red Sovine and Minnie Pearl--which is the Taj version(except for his bridge)--

or
||C C/F F/C C/ G7 G7||
Which is from a recording by Tenessee Ernie Ford and Kay Starr(a hot western swing version with Jimmy Bryant and Speedy West)

- or
|| C A7/D7 D7/ G7 G7/C C||--

which is basically the same as the "Salty Dog" progression--


This song has been done so many different ways that it is amazing--and everyone seems to have their own lyrics!!
