The blues band I play with actually usually lets things down easy by playing Will The Circle Be Unbroken. Start out slow with brushes and as it picks up I usually migrate to the 2nd line thing Russel Bautiste did on Scofield's version of Cissy Strut. It fits nicely over a straight 2/4 groove. We may take it all the way up to a praise beat but usually just speed up the 2nd line a bit. Then bring it back down with an audience participation tacit part, then go out moderately.
