I've been learning a simple clawhammer version of "Oh Susanna" and read recently that Neil Young and his band "Crazy Horse" were doing an album of American folk tunes. So I did a snoop and found this. Oh my! Stephen Foster would be turning in his grave. Not sure if the video is real but Oh Susanna will never be quite the same to me again. Not sure what Neil will do to the other tunes such as "She'll be Coming around the Mountain".
