The introduction to the Tijuana Brass cartoon "Double Feature" is a 45-second version of Mexican Shuffle. It ends cold, with a single drum beat. Could it be edited on from the opening vamp? A small thing but there you go. Say, has anybody, for their own amusement, made a fake stereo version of Shuffle? Highs in one channel, lows in the other? I did, and it sounded cool.
