Good songs to "jam" on?

[::::BASSIST::::]

I played with some dudes last night for the first time. They play "jam" style with a focus on RnB, but its really not that RnB. We played heard it on the grapevine, in the midnight hour, moondance, spooky, born under a bad sign. stuff like that. they jam the tunes out. for example, heard it on the grapevine went for 20 minutes.

What are some other good songs for extended jams?
