B.B. King , Joan Baez and other great artists came to New York's Maximum Security Prison, Sing Sing, and gave one of the best shows of their lives. B.B. called it one of his greatest performances. New York's Daily News called it one of the greatest moments in live entertainment.This entire film is a must-see. Get it at http://www.amazon.com/dp/B00061U15C. This clip is a portion of my feature-length documentary, Sing Sing Thanksgiving, recorded in 1973 at the prison outside New York City. We got permission to present the concert from the Warden and took full of it to create and then record this incredible event plus tell the lives of some of the inmates who helped make it happen.
