Re 18d: I’ve only heard the warning as “Just you wait”.
NO EXIT. Neat and simple. I’ve heard that exit signs are on the way out.
My favourite was RHAPSODY IN BLUE. Wonder if I’m the only one here who has listened to the version by Liquid Tension Experiment.
Thanks Filbert and Flashling
I really struggled to get going and might have still been if not for two lovely long anagrams which kick started me.
Filbert’s standard remains high: CANVAS, CORONATION (amusing def), TOLEDO, SOCIETAL (is the ‘s part of the def? Community can certainly be an adjective but I wonder if Filbert has ‘belonging to society’, hence ‘society’s’ in mind), SCULLERY, NO EXIT (delightful), SOAPSTONE, SUBJUGATE and OSCILLATE were my faves along with Hovis’s favourite, RHAPSODY IN BLUE.
I’m sure the Nina’s not intentional.
Thanks Filbert and flashling
@PM I debated on whether the ‘S should be included and in hindsight I agree with you, it’S NOT a Nina ….
Liked CORONATION, NO EXIT, SOAPSTONE and YOU WAIT.
Thanks Filbert and flashling
Delighted to see Gershwin’s RHAPSODY IN BLUE, a musical favourite of mine – more similar please! Like Matthew Newell @2 I struggled to get going (happening more often these days!) but eventually everything slotted nicely into place. Thanks Filbert and Flashling
Great puzzle as usual which I also struggled to start. TO BED is a favourite along with NO EXIT and SOAPSTONE. I loved ‘bad cops’ as the def for STASI and ‘confirming who’s boss’ is very amusing. Thanks for a comprehensive blog flashling and thanks to Filbert whose puzzles seem so effortlessly compiled.
Lots of earworms today. Apart from the Gershwin (2021 by LTE – Thanks Hovis@1),
at 27a there’s also Harold Melvin & The Blue Notes (1975) or Thelma Houston (1976) or The Communards (1986) or Maria from Blondie’s NO EXIT (1999)…
…But who could forget Clifford T Ward’s SCULLERY? (A No. 37 hit in January 1974, celebrating a 50th anniversary)
LOi and COTD: EWE ATE – 😀
Thanks F&F – F
Fun puzzle. I was held up in the SE for quite a while since I confidently entered DECADENT for 26 (DEC on A + DENT for cavity), and couldn’t see what was wrong. I only fixed it after seeing the hidden in 17d and thinking that that looked like a word, a hunch which was confirmed by a web search.
I meant SW obviously. Oops
I had FrankieG@9, until you went and mentioned it.
Hoping for a Jaguar XJS theme when 21a went in. Too niche maybe.
The dining ovis LOI here too. Lots to like. I’m off to see what a LEISTER looks like.
Thanks Filbert and flashling.
Thanks both. As usual with this setter, I did not make quick progress, but got there in the end. I didn’t know AMOUR as adultery per se, but more as something secretive , perhaps for more innocent reasons, and FAIR DO’S I thought simply meant ‘fair enough’.
Lots to like – SCULLERY and CORONATION and a reminder of RHAPSODY IN BLUE. Thanks for the link Frankie G
‘Preserve huge painting’ made me think FREEZE or FRIEZE. But no.
Thanks both
In 5d I took ‘fair’ to refer to exhibition, as in trade fair. Good fun – appreciate the puzzle and blog.
Yes EW that’s what I clumsily was trying to say.
Yes, another great puzzle from Filbert.
