These are recent finds on Ebay. Chuck Willis and The Drivters, on 78 RPM vinyl. Yes, vinyl. These records were distributed by Jukebox Junction Inc. Demoins, Iowa, 1981, courtesy of Atlantic Records. Both records are in mint condition.
I'm sure there are those who already know about these records, but this is a new find for me. The fun of collecting records is that there will always be a surprise out there somewhere.
