A five-minute feature film here from Neil Young. Not sure about one or two of the rhymes, but there’s no denying the cinematic power of the central image.
We’re in the original key of G, but I found an unusual tuning to be able to get the main guitar figure. I have no idea what to call it, but it’s CEGDBD. Tuning the A string all the way down to E means it gets quite loose, so I put an E string (a 53, iirc) on there, which firmed it up quite nicely.
