Those "Happy Crickets" you were forbidden to listen to out-of-season didn't only *sound* like Alvin and the Chipmunks, they perfomed Alvin's first big hit word-for-word ("Christmas, Christmas time is here ..")

"Alvin" and his backup-singing rodent buddies were speeded-up multi-tracked vocals recorded by one David Seville, who made cameo appearances in his unadulterated voice as the Chipmunks' long-suffering pet owner.
