who sings the song in the magners ad that goes 'what's a fella to do cause her hair is black and her eyes are blue.' i think it's steve earle but i'm not 100%
To be pedantic, although Steve Earle wrote and sings the song, the version on the ad is actually credited to Sharon Shannon, featuring Steve Earle. Sharon Shannon is the fiddle player on the track, and the song is the lead track on her "Best Of" compilation.
