OMG I'm old. I bought the album Nashville Skyline with Lay Lady Lay on it. I can't remember 45's still around then. Four songs on it I still see posted all over iHub and here, including one of you fav's Salty, ""Girl from the North Country" (duet with Johnny Cash)

The sad thing is that Bob could still sing then with a mild voice, not sure when the raspiness came in.
