I saw Brad Nowell with Sublime too. He spit on my friend! We hated him … until he died.
Maynard Ferguson
Mark Sandman of Morphine on a really small stage in Columbus somewhere.
Gosh I feel so young compared to a lot of you 
I saw Stevie Ray Vaughn seven times. I have his autograph.
I saw blues great Johnny Copeland. I think it was his last performance before he died. His daughter had to finish several songs for him because he was so sick.
Never saw Frank Zappa play unfortunately. I did see a free lecture he did at my college.

Ramones,

Garcia
John Lee Hooker (not rock but…)
These for me, as well, plus:
Kurt Cobain
Shannon Hoon (of Blind Melon)
Can’t think of any others right now.
An Arky, I did NOT know that John Panazzo, Karl Mueller, and Rob Buck had died (damn, I’m out of it!) Them too.
Kirsty MacColl
It seems like someone my age should hve a longer list.
John Bonham
( No Led Zeppelin on this list yet?)

I did go see Jerry Lee Lewis over 20 years ago to be sure “I saw him before he diied”. But the Killer has lasted longer than anyone figured.
Freddy Mercury (several times)

James Dewar (Robin Trower)

Bobby Sheehan (Blues Traveler)
Michael Houser (Widespread Panic)
I know there are more, but this is way too depressing.
Were you still in SoCal back then? If so, I was at the Coliseum that day too! Now if T-Bone Burnett would die, we’d hit the trifecta for that day.
Terry Kath (Chicago)
Carl Wilson (Beach Boys)
John Denver
Dottie West (OK, actually a country star, but she did have one pop hit. Ask me sometime to tell you about how I had Dottie West alone with me in my Camaro Z-28…and let me brag a little…)
I don’t expect too many folks on this board to know who the band Fludd was, but they are legendary from having been in The Canadian Invasion in the early-mid '70s. They were about as close as we got to glam. Founding members of the band were Brian and Ed Pilling. They played at my high school, and I saw them later at the Canadian National Exhibition. Brian Pilling died of cancer in 1978, and the band broke up for good.
(Another founding member, Greg Godovitz, went on to form Goddo. I haven’t heard about anything from Ed Pilling since he lost his brother.)
Bah and I had tickets to see him just a few shows later here in Seattle,
Andrew Wood, mostly local star, he was the Singer for the band that became Pearl Jam (mother love bone) Saw them at an old skate king along with
Lane Staley from Alice in chains at the same show,
Didnt exatly see them but I did work backstage security for Nirvana.

John Bonham
John Entwhistle
