Unfortunately, these are the versions of the Duson waltz I know of:
1. Duson waltz. Aldus Rogus and his French Accordion. Diga ding ding dong. Goldband Records. G-1084. n.d.. 45.
2. Duson waltz. Pat Savant & [and] the Louisiana Playboys with Joe Turner. Duson waltz. Kajun Records. 1028. . 45.
3. Duson waltz. Fred Charlie and The Acadiana Cajuns. Je Reve Heir Au Soir. Acadiana 0143. CD.
4. I think Jamie Bergeron also recorded it, but I've never heard his version.
Valse the Bayou Chène (Iry LeJeune or Eddy leJeune)
La Valse qui m' fait du mal (Lawrence Walker)
I have that from the book of Raymond Francois and checked at the cd's.
Neal, I got an email from Ron who had run it through some software he had and it's now playing through both speakers. I'll try out the download again to see if what you did worked for me though ! thanks !
