Ed Poullard told me he learned from his father, who was influenced by Ambrose Thibodeaux, among others. Don't know if that helps! On the Les Amis Creoles cd Ed does Long Point Two Step, which was on Ambrose Thibodeaux's yellow album.
I don't know who else Uncle Ambrose influenced directly. He played on TV on the Passe Partout show on Channel 10 KLFY, so he was known all over the place and probably influenced a bunch of people, if not for style then for repertoire.
Sound like you have Ambrose Thibodeaux's first album, Authentic French Acadian Music, ~1963. The yellow album is his second one, More Authentic Acadian French Music, LL-119, ~late 1960s. The La Louisianne Records Web site still sells these lps.
