Let‘s not forget that ELVIS PRESLEY only "loaned" HOUND DOG from BIG MAMA THORNTON, pictured here in the middle. She recorded the song on the Peacock label three years before PRESLEY laid hands on this classic. I.m.h.o. THORNTON offered the much better version. This great shot is from circa 1965 and was taken by JIM MARSHALL. No matter what I really LOVE these tunes! Other persons on this photo (as far as I could identify them) are James Cotton, Otis Spann, Samuel Lawhorn, Luther Johnson and of course Muddy Waters. To quote the latter: This is "stuff you gotta watch"!
