CAJUN ACCORDION DISCUSSION GROUP
Not sure if its the same you tune you are looking for but Amede Ardoin recorded a waltz labeled Oberlin. You can find it on the "I'm Never Coming Back" album.
Cory's Oberlin & Bois Sec's Oberlin are the same. Amedee's Oberlin is different. JB
Cory got his version from Bois Sec, but he sure plays it differently
