Yes you do have good rhythm with that familiar song, and your drummer knows the changes. I remember your posting a tutorial on how to play "Madame President", and that was good too. But can you keep it interesting in a 2 hour jam? The crowd listens to the singer and sings along, but can you entertain your band?
I've seen 2 or more hour blues jams, but you don't have a blues drummer right? Sure he can be subtle, but energetic music is his strength. You must learn more rhythms, particularly world music, to keep your funk interesting.
