I'm just catching up on this thread, but I really love this image!!
Only four tracks were recorded at that '51 session: "Howzit," "Nails," "Little Pony," and "Beaver Junction." Presumably issued on two 78s? Or was Columbia doing 45s by then? Columbia did reissue two of them ("Little Pony" and "Beaver Junction") on its "America's #1 Band" comp.
