In 2007 Legacy Records released a box set titled At San Quentin (Legacy Edition). I have recently read the Michael Streissguth book "Johnny Cash at Folsom Prison: The Making of a Masterpiece," and came to know that the whole concert hasn't been released yet. It may take a couple of years, but Legacy should realease a box set " At Folsom Prison (legacy Edition)." The complete Folsom Prison Performance of January 13, 1968. Both shows. The morning and afternoon. I realize the reason Columbia Records didn't release the full show in 1968 is because a bunch of the songs are unfinished, but us Cash fans love obscure stuff! We would love it if Sony released the complete 2 shows At Folsom Prison. Uncut! No overdubbs!
