Sorry for the delay, busy weekend. A bar mitzvah, my now-three-year-old’s birthday, visiting inlaws and mother, and a Joan Osborne concert, all excellent. It was the first time I’ve seen Joan Osborne live, by the way, and let me just say she is awesome in concert. Anyway on to the puzzle.
The title was “All Saints’ Day”, and it was a hard one. Despite my guessing that the letters ST figured in the answers, I still had a pretty tough time. And I got two squares wrong in the end. 100D, “Old Indian V.I.P.” was NAWAB. I thought it had to be RANEE or RAJAH, but the W in WHERE at 115A nixed that. I should have been able to figure that 99A, “Composer Dohnanyi” was ERNO, not ERRO, but I had no idea what the key of Bach’s best-known Mass was (125A, BMINOR). This all makes the Indian V.I.P. NAWAB. What? Never heard of it. Bah.
So, the theme answers:
23A, Switch in an orchestra section? – EXCHANGEOFSTRINGS
40A, Pilgrim? – HOLYSTROLLER
57A, Neolithic outlaws? – STONEARMEDBANDITS
77A, Invisible lost dogs? – ULTRAVIOLETSTRAYS
96A, Gets fat? – GOESALLSTOUT
115A, Go-go club? – WHERETHEBOYSSTARE
16D, Add new connections between floors? – PUTONSTAIRS
70D, Dieter? – STARCHENEMY
