Some more incredibly rare video of the late, great Stevie Ray Vaughan in action has suddenly become available on YouTube.
Below, watch Buddy Guy jamming with Vaughan on July 30, 1989, at Buddy Guy's Legends in Chicago.
The event? Guy's 53rd birthday party.
This video mysteriously appeared on YouTube March 19. We think the top commenter (on YouTube) puts it best:
"Wow is all I can say!!!!! I've heard this was video taped from a few people, even saw a couple grainy photos from said video. But I never thought any of this would see the light of day! Please tell me the whole thing was recorded!!?"
