“I was told that some of you dudes don’t know anything about blues. That’s what they told me. So I wanna say this to you: I came to swap some with you. I imagine that quite a few of you dudes have the blues already.”

BB King called his Thanksgiving performance for prisoners at Sing Sing in 1972 the greatest performance of his life. This remarkable live footage captures it. It’s been called one of the finest moments ever in live entertainment — so whether you’ve got the blues this holiday season or not, have a listen to one of music’s greatest performers giving the performance of his life.
