DAVID SEVILLE - Alvin's Harmonica b/w Mediocre

A very early Ross Bagsdarian single. He did rockabilly before this ,and I think the "Witch Doctor" single ,where he first stumbled upon speeding up the vocals. I believe this may be the first appearance of Alvin and The Chipmunks ,but I could be wrong.
