Lawrence Walker's Osson Two Step. Not to be confused with Joe Falcon's Osson One Step. Osson One Step is loosely based on Rubber Dolly. So is Bayou Pon Pon, High Point, Janot Special, Two Step d'Osrun, etc. Some more loosely based than others.
I'm not familiar with Joe's version of St. Landry, which is Ardoin's Opelousas, Aldus' Duson, and Iry's Chene.
I've know a rare song by Jessie Lege "Fais do Bebe", which is the same tune as "Tit Mamou" and the "Cankton Two Step" but slowed down to a quick waltz with different lyrics. Not to be confused with "Fais do do bebe" which is about cotton and soybean fields, better known as the two step "Le Range Coton".
Never heard of "The Black Smith Two Step">>"Two Step de Forgeron" by Sidney Brown. Cool Title.
