I'm trying to learn a coupla' songs from Jimmie Rodgers's CD "Train Whistle Blues." I can't really figure out what chords he is using. The ones I am trying to figure out are "Hard Time Blues," "High Powered Mama," "New Orleans Blues," "Train Whistle Blues." Of course, I need the chords for the yodeling part also. Any help would be appreciated. Cheers, folks.
