I've heard pete do that before, sometimes he gets stuck between the song that just finished playing and the one hes about to play . It happens to the best of us. But I will say that Peppy plays only wet tuned Acadians on those cd's.
It was in all likely hood Kristi Gillory since she is the accordion player for the Rythem Devils and she plays on an old "Creole" accordion, thats the brand name "Creole".
