George: we can't possibly be the same person because we disagree fundamentally about which concert contained which concerto!
I have 2/11/73 recorded as Don Juan, Chopin conc 2 with Michael Roll, and Tippett. I think I was on my own for the Campoli/ Atherton one
My position in the Tippett IIRC was about 1/4 of the way round the semicircle of the top deck - from L to R, as you look at the 'flat end' of the hall with the big doors through which one waltzes in and out to collect one's degree. IIRC, assuming one had a degree to collect.... Watched my elder daughter do it (video only - we were snowbound in Cornwall at the time) some months ago. As for my own show, I can only remember being the one who most seriously got my bow antiphase and widdershins
I was at Balliol, originally a Chemistry exhibitioner in 1972 but switched to Eng Lang & Lit 1973, graduating in 76. I deduce you may have done something a little more musical? My performances were restricted - fortunately for those who actually LIKE music
- to Balliol chapel choir (refounded 1973), plus a few college choirs that didn't have auditions, for particular 'big choral work' performances (Trinity and University come to mind, as do Faure Req + Walton Te deum (1972), Dream of Gerontius, Beet Choral Sympathy). Did we (or our spouses) breathe the same air there too??
