I'm playing a really groovy, mid tempo swing song by Marion Black called Who Knows. I play at a lot of open mics and similar things, but it's just me singing and playing guitar. I'm wondering what people would play for rhythm during that song. There's a really simple walking bassline that would be really fun to work off of, but it would get too old to play through the whole song.

The chord progression goes

|-Dm----|-F----|-Gm-----|-C-----| Repeated through the verses and

|-Dm----|-------|-Gm----|------| in the chorus.

I've got plenty of lead ideas, but i need help thinking of rhythm licks to go with it.
