My wife's uncle is a professional photographer who specializes in concerts. I asked him if he ever had a chance to photograph Led Zeppelin and he said he saw them when they played in OKC in 1977. He sent me a couple of photos of Bonzo that he had on the roll. Got them framed and up on the wall today. He's playing the big stainless set and I noticed he had an extra crash behind the 18" floor tom.
