Hey, This Guy's Good

OK, so you know how Steve Martin is basically a full-time bluegrass musician/composer now?

Pretty Little One feat. Edie Brickell.

I've long wanted some short film or tv-episode adaptations of Manly Wade Wellman, but now I want Martin involved, because the man clearly knows his Appalachian murder ballads.

ETA -- Wikipedia describes the album as a collaboration between Martin and Brickell, so she may be the one who wrote the lyrics.
