[Harp-L] Harmonica in The Ballad of Buster Scruggs

[Shuffling]

Coincidentally, I just saw the movie for the first time this past week and was wondering the same thing.
I don't have a definitive answer, but I think the player might be Willie Watson, whom I don't know anything about (https://en.wikipedia.org/wiki/Willie_Watson_(musician)).
BTW, in the first film in the anthology, I though it was very cool that it was a harp player who ultimately bested the guitar player.

Hi List!

Does anyone know who plays harmonica in the song that Willie Watson sings in the end of the first episode of the Coen Brothers film "The Ballad of Buster Scruggs"? It is a really well played and tasteful country-styled diatonic.
