Yes that was me, were you the bloke in the paisley shirt ??
I get the impression people are surprised at us ol’ fella’s seeing these bands. It was very different in those days, the venues were small, often a pub back room, a few hundred people, the Marquee was licenced for 350 if I remember right, the first Hendrix gig was really packed & was recon’d to be well over 1000.
But back to the point, most gig organisers put on numbers of bands. Places like Marquee, 100 Club, Eel Pie, Speakeasy all had numbers of bands per night & it was common for any non playing band people in the audience to get invited up to jam. I’ve seen sessions with over 12 very well known faces on stage.
One London venue that I really enjoyed & saw a lot of bands at was Middle Earth (the Roundhouse) it was an all nighter & put on some great nights, just take a look at these tickets,
