The only good disco song was Zappa’s “Dancing Fool.”
That was coming-of-age for me and my big brother.
One night we went to a disco, because we were bored. And besides that, it was Cheap Pitchers of Beer night.
So we're sitting there having our beer, watching other people dance. There's a young guy out there who looks and dances just like John Travolta. He was pretty good actually, but we were into rock'n'roll, so we were contemptuous, as required.
And then the DJ put Dancin' Fool on the turntable, whereupon Travolta gets all pissed off, and stomps off the floor.
You know you've had a good laugh, when you wake up the next morning, and your stomach muscles hurt.
