Link #2 is Ganey at the Liberty Theatre in Eunice.
Not a good view at the right hand :-(
But maybe you cabn do something with the sound.

There's a YouTube of Lyle Guidry below that's okay -- a bit better than the Ganey / Liberty Theater one in terms of right hand view, and maybe a little easier to pick out the accordion (it's just accordion + acoustic guitar), but it seems to have been recorded as the sun was setting (gets darker over the course of the video) and it's not something you can really work off. Still, I like his version of the song.
