Not to be confused with Billy Graham, the evangelist, Bill Graham is the concert producer resonsible for nearly every big name concert tour in the US in the 70's and 80's. He has worked with such groups as the Grateful Dead, the Allman Brothers Band, the Rolling Stones, and Led Zeppelin. Although he never recorded a song, he was one of the most influential people in rock history. He also owned and operated the Fillmore.
