Some notable omissions:
Rory Gallagher... journo asked Hendrix at the Isle of Wight "What is it like to be the greatest guitarist in the world?"... "Dunno, ask Rory Gallagher" was his reply
Ritchie Blackmore... invented the heavy rock genre, learned to be a showman with Screaming Lord Sutch and Jerry Lee Lewis touring in the early days
Big Jim Sullivan... taught Ritchie and Jimmy Page
Shuggie Otis...son of Johnny, big impact as a blues protege when he recorded his first album when 17 in the mid 70s but got into some substance abuse, saw him at Manchester Academy about 5 yrs ago and was not disappointed
Robin Trower... never stopped working still recording and touring to this day, he is now in his 70s, now well into a bluesy sound
