I was there for one of those first London (Hammersmith Odeon) concerts back in 1982 - possibly the second of two performances that night. Huge expectations in the crowd, as I don’t think he had played a major London UK since about 1970 (Isle of Wight, I guess). What I recall is that it wasn’t very long (one set, just over an hour), Miles looked very frail (not expected), emerging onto the stage with walking stick and that Mike Stern was featured very extensively in Van Halen mode. Wish I’d been closer to the stage, my seat was well back. I’ve got recollections of someone shouting out ‘play some jazz’ at one point.
I remember being surprised by just how boppish/straight ahead ‘My Man’s Gone Now’ was - and the fact that he even played it at all. That performance was a highlight of the show (along with a lengthy-ish ‘Ife’). Inconceivable during the ‘Agharta’ period.
Ian Carr’s book had also just come out before this show so I always associate this concert with reading that (excellent) book.
