Can somebody explain the sudden (re)popularity of the "Chicken Dance" to me? I'd never heard of it before a couple of years ago; now its on all my kids' records like its something that little kids have always listened to.

Old songs don't just come back out of nowhere on their own; somebody re-popularizes them. Think of what Tarantino did for "Stuck in the Middle With You". Who is responsible for the Chicken Dance?
