The Bad Boy's Band Ver A best, new end

Recreate with a a nice ending riff. Do not change the rest of the piece. A late 50s style rock and roll band playing a powerful warm-up piece for a show and dance. Only one electric guitar, but 3 Sax players (one a deep base) heavy rock and roll drum work, particularly with snare drum. A tune of that era ties the piece together. A down and dirty style that parents of the 50s would not approve, The beat, the beat THE BEAT, Using know rythem and blues riffs that fit.
