Don't know exactly where to put this but I think it's amazing that you found some footage (or soundage, I should say) of Rory Gallagher.  I'd seen him twice in the 1970's, once as the opening act for Dave Mason and once as the opening act at Shea Stadium for Robin Trower and Jethro Tull.  An amazing live performer, he left us way too soon.  Thanks for the memories.
