Christian, have you tried the archives to see if they have anything on him? You can search his name. I remember the show well, sure wich I had been recording it.
Another source would be Pete Bergeron at KRVS. And Cecil Fontenot at Floyd's Records in Ville Platte (Evangeline Parish).
And then start asking some of the older musicians still around..Marc and Ann Savoy would know about him. Tina Pilione at Savoy's music center did quite a bit of research of the early fiddlers in that area too.
