ACROSS
1 WHO OPS I remember these two songs by the Who very well so this went in straightway - ops being musical works (though I’m not sure if that term would have been used very often for Who numbers!)
9 MIT HER Massachusetts Institute of Technology. A new word for me that I worked out from the wordplay, verifying after.
10 AMARETTI (not AMORETTI) Learned today, when verifying, about Amoretti (later:Amaretti!) cookies for the first time - eatables. A little puzzled with “talked of” in the clue as it seemed a double definition without a homophone element, but I may have missed something (Later: I did!). “Lover boys talked of these Italian cookies” (Later, Answer is AMARETTI, I think as “these” Italian cookies so there is a homophone, the lover boys “talked of” as Colin has explained, thanks to him)
11 NOIS(om)E Tricky - out of order means take away OM = Order of Merit
12 MINOR SUIT “Miner” Clubs is a minor suit in the card game bridge.
13 SLEEVE NOTES ! Favourite clue.
17 R ((ASTAF) ARIA) N Good misleading context with RN = Royal Navy as the service, not one you pray at. (a fast)*
22 GIG UE EU gig< though gig, as a palindrome, does not change, the clue is perfectly sound.
23 DOORNAIL i = one in (Orlando)*
24 SIR I US I = (electric) current
26 SHO(t) GUN
DOWN
1 W (OMAN) ISH tour is a containment indicator
6 CARER Would need extra energy (=e) to give career = long-term work.
12 MINIS(T)ERIAL Lead for Tony = T Miniserial an adj from miniseries.
15 SING SING Notorious prison in New York sing = inform
16 ANDERSON Hidden - Anderson air raid shelters (WWII)
18 T (RADE) R Mostly ready = (read)* tr (abbrev) = transactions
19 ON FORM Or is it “in form”? After some thought settled for the former, but it’s a close-run thing and won’t know till tomorrow. I think both would fit “well” (Concise OED confirms) but “on” might fit the second part “where people often write personal details” just a little better, perhaps.
21 YONK(er)S Monarch = ER Yonkers a city of New York
