As above, I have a different perspective on the show. While, yes, Hendrix did cut the set short due to the flu, it was a great concert — not just because we (read my girlfriend) got personal attention from the guitar god, but because some renditions were enough to stick with me through the intervening 55 years. Red House in itself was ecstasy, but I think I left my (16 y/o) body during the opening bars of Are You Experienced … I was afterwards!
Hendrix was also miffed at the cretins who kept shouting for standards while he wanted to spotlight more new work from Electric Ladyland. I risked injury to tell them to STFU.
As for the support bands; they were excellent. Eire Apparent were good, Soft Machine were too short–so good I bought their album right after. Still have it.
Vanilla Fudge were almost de rigueur, opening, it seemed, for almost every concert I saw in those days, including The Mothers of Invention and Led Zeppelin.

Zenora Rose Hendrix Moore also lived for a time in a small house on McGill and Wall
Street in Vancouver.
We lived across the street and ‘Aunt Rose’, as I called her, and my Mom were good friends; as children, Jimi and I played together.

This is almost for sure fake info. Jimi’s moves after his army period are well documented, and there is no evidence to suggest that he went all the way to Vancouver. The only time Jimi was in Vancouver as a kid [usually with his brother Leon] was during summer periods. He did go Dawson Annex but the only attendance record that could be found for that is for September 1949. According to Pearl Hendrix, Jimi was at school there the most “for two months” but I believe it must be longer as here is a gab between that Vancouver period and when Jimi went to school in Seattle. Records kept on schools in Saettle are very accurate and complete. The only period not complete [i.e. pre Seattle] deals with the kindergarten period.

I can add another personal note to which can’t be deduced from listening to the concert recording (I discovered it a couple of years ago and embedded it in my own story linked here). He kneeled on the edge of the stage and played Foxy Lady to my girlfriend, who was sitting in front of me, beneath the stage. I also have the ticket stub, a treasured memento.

. . . saw Lou Reed and the Velvet Underground at the retinal circus, opening for the Collecters (became Chilliwack). Howie Vickers and the Collectors performed a 2 hour version of their “What Love Suite”. When we left the venue after they finished the sun was just coming up 😉

Circa 1975, while working part-time at the City Nights (aka Old Pantages) Theatre, I’d sometimes drop by the nearby Smiling Buddha Cabaret for a nightcap. A musician or three claimed they always had to negotiate hard with the owner who’d try to persuade them to take less “because Jimi (Hendrix ) played here on his way up.”

If anybody can find a class photo of Jimi in his Dawson Elementary days, I’d sure love to see it.
