It wasn't 40 years ago that Sgt. Pepper taught the band......

It was the Man in Black doing the concert behind the walls at Folsom Penitentiary. His career lasted almost 50 years. I have a couple DVD's of his concerts and most of his music loaded in my IPod. I could not find any video of his concert at Folsom but this YouTube segment of Johnny and Willie doing one of Cash's classics is a delight, just two old friends enjoying performing together.

BTW Johnny Cash was a Democrat and a good friend of Jimmy Carter.
