Goats.
When you get to the fade out portion do what we did:
The lead singer would give a little nod offstage right. This was the cue for our Goat Wrangler to leap into action. He would wave his arms and stamp his feet causing a herd of 5 to 17 Goats to stampede across the stage from right to left.
The clomping of hooves Would distract the audience while we looked at each other, shrugging our shoulders and mouthing, "What do we do next?" If we couldn't think of anything the singer would nod offstage left where our Assistant Wrangler would repeat the whole concern but in reverse.
Sometimes this would go on for tens of minutes until someone with a mic would yell, "Stop! Stop playing everybody!"
You might have to help, wrangle, a few recalcitrant Goats offstage but that's no big deal. Usually.
Maybe give it a whirl?
