John Lennon / Plastic Ono Band or Yoko Ono / Plastic Ono Band?

From what you do hear, Bo Diddley sounded the best to me.

sounds about right!

My Dad (a David, but no brother Glen) told me he had been at this. I’m on the fence as to whether he actually was but it’s still nice to think about.

That's great. Do you know if he was also at the Toronto Pop Festival a few months earlier? (The Velvet Underground and Sly & the Family Stone!)

Small chance your dad turns up in one of the crowd shots--you should see it.

The footage I've seen from that concert was pretty amazing. Little Richard especially (which was also used in The Little Richard Story a great film by William Klein. I think it was the first time I ever saw Jerry Lee Lewis play guitar - his set was good. I've only seen brief bits of the rest, but I'll have to check out Bo's.

Which concert -- Toronto Pop or the other Toronto show?

Never mind. There's this:

Yeah, that's the one! I remember the outfit. FWIW, the one time I saw Little Richard in-person, he had the brightest, shiniest and most sparkling shoes I had EVER seen. Never mind shoes, of any piece of attire worn by anyone.

I will watch them and look for him, he was only about 15 in ‘69 though so doubtful he was at anything earlier. Sadly I lost him a few years ago so can’t ask :(

Oh I misread and thought the other was a couple years not months earlier

Ritchie Yorke turns up in Marcus's column today, and also in Revival69--at one point, he was instrumental in saving the whole show. Made me laugh, because Yorke became a running punchline for a friend and I who both remembered his book Axes, Chops & Hot Licks, a look at Canadian pop in the early '70s. It was one of the few rock-related books that might be in your school library in the mid-'70s, at least if you were Canadian. (Yorke was Australian, but he moved to Canada and wrote for the Globe and the Telegram.) I don't know if either of us had even read him--I have a copy of Axes I bought later--but based on his 10-favourite list in the first Paul Gambaccini Top 200 book, we decided he was a good stand-in for a certain kind of '70s rock critic, best described, maybe, by the joke in Annie Hall about achieving "total heavy-osity." Very unfair, no doubt. He died five years ago.

He was included in the list of "10 Worst Rock Critics" that Marcus wrote for the Book of Rock Lists in 1980, I can't imagine that the passage of time has made him more beloved.

I'm sure that was part of us seizing on him in particular.
