Here's what I use:

Well if you ever been down to New Orleans (G C7 Db7)
Then you prob'ly know just what I mean (G E9 Eb9 D9)
All week long they're as quiet as a mouse (G C7 Db7)
But on Saturday night they go from house to house (D7 G)

All the sevenths are like first position C7, just move it on up the frets. The ninths are movable too (E9 on the seventh fret) or you can use sevenths instead of ninths. Just listen to the bass line and you'll see where to move the chords.

Gotta make it swing, Chet
