I’ve seen him (Seattle).
Saw him at Harper Junior College, Illinois in about 1976 or 1977 and kissed him on the cheek (with his permission).
I’ve seen Jerry Lee Lewis, Chuck Berry, and Little Richard.
All three were on the line-up at the ‘Rock n Roll Revival’ in Toronto in September 1969. (I had a behind-stage pass, or what passed for one. Chuck offered me a KOOL. (Now that was cool.)
And the Plastic Ono Band, I assume.
No, it was the Icehouse song “Electric Blue”, which was recent at the time. It seemed like a very odd choice for them to do.
Wow. Around that time I saw Redbone open for David Bromberg. I was there to see Leon, but most of the crowd was there to see Bromberg and had no idea who Leon Redbone was (not SNL fans, I guess).
It was cool seeing people being amazed by Redbone and wanting an encore.
Wow, no kidding! I sometimes wish I could relive that one, I would have a greater appreciation for the Band. I knew Up On Cripple Creek and The Night They Drove Old Dixie Down, and that’s about it.
I’d give us better seats as well. We were up near the rafters on the right side of the stage, about half way back.
The Paramount in Seattle, holds about 3,000 people. They opened for The Hollies.
Anyone else see KISS? I saw them in Seattle in 1976.
Did anyone see Humble Pie circa 1973? My first concert when I was 15 or so.
Anyone else see Randy Newman? He opened for Steven Wright when I saw him. The energy was all wrong and the audience didn’t enjoy it.
IIRC I saw Randy Newman when he played a local college. Good show, if rather sparsely attended.
I’ve not seen X but I have seen John Doe solo and Excene Cervenka with Lydia Lunch reading their poetry!
Back in April 2004,Robert Moog giving a talk with Jean-Jacques Perrey playing and demonstrating Moog synthesisers.
Roughly the same time, Karlheinz Stockhausen; he spent ages fine-tuning the sound from a whole range of speakers all round the auditorium and slung from the ceiling for an immersive effect. Then he told us to close our eyes to listen to the music.
I suspect others saw this too, but The Lamb Lies Down on Broadway tour by Genesis back in 1975. Very strange! 
And the Resident’s Mole Show! Fairly sure others have seen that as well though…
Saw a concert that nobody was at. My friend’s band ColdShot played at a bar in Ford City in 2001. We did this “thing” where my friend told the venue that I was their sound guy so that I got free drinks. We did this everywhere.
That night I met them at the bar early and helped set up the stage. The Penguins had a playoff game, so the bar expected a smaller than usual turnout. Top that with a freak snowstorm that dumped a ton of snow, and the only person (other than me) listening to the band was me!
The band played two long sets, then goofed around on stage, waiting for the road crews to make roads passable.
Lotta X fans in this thread, I love it! Wish I could have seen that Lydia show, always liked her.
First time I saw any of them live was at Bob “supermasochist” Flanagan’s public wake in Silverlake, and Exene took the mike for a freeform rant. No wait, I’m wrong…when I saw Syd Straw opening for Camper Van Beethoven in 1989, D.J. was drumming for her.
I’ve got one that nobody has mentioned- Black Oak Arkansas! 
Hey, give me a break, it was my first concert, in Sheboygan WI 1972. They did have a very talented young drummer named Tommy Aldridge who went on to have quite a career in hard rock and heavy metal. He did a loooong drum solo and about 2/3 of the way through he tossed the drumsticks into the crowd, then finished the solo with his bare hands. I caught one of the drumsticks and I still have it.
I saw Chapman and Thompson, and I’ve seen Kurt Vonnegut twice. I saw Zappa in concert once but never on the lecture circuit.
I saw fiddle player Papa John Creach. If I remember right I went by myself to that show because none of my friends were interested. He looked old and frail but damn he could still play.
In a similar vein, I saw Terry Riley in concert a few years ago. Quite an enjoyable evening and a very mellow vibe as expected.
I was part of the group that brought Vonnegut to speak at our campus, and spent ten minutes alone with him. He was very, very drunk. But otherwise a pleasant chap.
When I saw Hunter Thompson a student brought a chair and a small table on to the stage. Then they brought a glass, an ice bucket and a bottle of Chivas. Thompson came out, spoke until the bottle was empty and then left the stage.
Well, maybe not in WI, but I saw Black Oak Arkansas in Boston on that tour…and then twice more in the next couple years.
I’ll take a chance with one: Jeff Wayne’s War of the Worlds, Liverpool, November 27, 2014
