Thanks Chandler and scchua
Mostly fitted the brief, though Midge Ure is pretty obscure for a Quiptic (Vienna was a great track, though!).
I went to a WI meeting once, to hear a nurseryman – a friend of mine – give a talk on alpines. I was made welcome!
Enjoyed this – Chandler is a very reliable setter of Quiptics, just challenging enough to be interesting and all very neat.
Thanks for the blog, scchua, especially the explanation of Midge, which I didn’t know – always assumed it was one of those Scottish names like Ming (Menzies).
Couldn’t parse LEGAL, hung up on EG for “say” and thus unable to account for the initial L. Obviously, I’m not a cricketeer…
All complete, but I failed to parse ‘lure’ and ‘legal eagle’. I found this trickier than the cryptic.
My knowledge of things British was not adequate to enable me to complete this — Women’s Institute, Ware, The Dandy and Orfe (which I still don’t understand after coming here). I didn’t think the clue for PICKETING was cryptic.
GdU
ORFE is a species of fish often kept in ponds. A lot of “goldfish” are Golden Orfe. Orfe is an alternative name for that most well-known crossword fish, the ide.
Thanks muffin. I got that one. My mistake — it’s 21a URE that still has me befuddled.
GDU – Midge Ure is a Scottish musician who was a member of Visage, later front man of Ultravox. Also involved in Thin Lizzy at one time, I think, and had a solo career too. Also one of the main people behind Live Aid.
Thank you, Widdersbel.
Almost but not quite Quiptic fare in this solver’s opinion – ORFE is new to me, and I wasn’t aware of F=fighter until now although it makes total sense once pointed out.
Liked HALFWIT, LURE, NEST EGG, STALLION. Only partly parsed LABYRINTHS and WARDROBE.
Cheers both.
GDU, Widdersbel : Jim Ure’s Christian name was turned backwards to Mij to avoid a clash with Jim McGinlay, bassist, when they were both in the Scottish group Salvation. Later came a refinement to.Midge.
Liked LEGAL EAGLE and also found myself thinking about Maria Eagle MP ( constituency near where I grew up ) – who really was once ( a nicely punned ) LEGAL EAGLE.
…. and cricket and debate about knowing terms versus spurning the subject is at large once again ….
Failed to parse LEGAL EAGLE, and F for fighter is new to me. Sorry to see that the current dismal fashion for grey as the default NEUTRAL colour has spread to crosswords – I preferred magnolia.
This was quite tough for a Quiptic. I was almost temoted to give up on the SW corner.
Failed 8d – never heard of this 1930s comic.
I could not parse:
7d apart from OB
19d apart from H in A GAST
15d and 27ac did not seem to be very cryptic to me.
New for me – F = fighter (in 2d).
Thanks, both.
[michelle @13
The Dandy comic was still published up to about 2010. When I was young and could spend my own pocket money I used to get the Dandy, or the Beano (which I preferred); when my parents bought me a comic, it was always the more uplifting Eagle!]
Never heard of the town WARE or the comic THE DANDY.
I don’t understand LURE. L = liberal, Google tells me that there is a musician called Jim Ure whose stage name is Midge/MIJ. What does the MIJ part have to do with the clue?
Once again I missed ON = LEG. When will I ever learn?
Thanks, Chandler and scchua.
WARE is probably most famous for its great bed.
I ran into the same problem with “legal” as Blaise at #3.
Got there in the end, but I can see how it would be tough for our overseas friends. WARE I’d heard of but didn’t know where (ware?) it was, and I was thinking ‘Ike Turner wasn’t Scottish, was he?!) before L-IKE became L-URE.
I didn’t realise the Dandy wasn’t still going, as I had grown up with it (although I always thought the BEANO, from last week’s Everyman, was cooler).
ORFE was new to me but couldn’t be anything else and I never knew Midge Ure was Jim! I always thought it was one of those weird Scottish nicknames, like Shug for Hugh or Doddie for George.
Also technically the WI isn’t (or wasn’t) an all-female group … https://www.youtube.com/watch?v=54uNKBOB9PU
Valentine @15 — Despite what you say, I do think you understand LURE. It’s just L (“Liberal”) + URE (“Scottish musician”). The facts that his first name is Midge and that that came from a phonetic reversal of Jim are not relevant to the clue.
Like Geoff Down Under @5 and michelle @13, I can’t see how 15dn (PICKETING) is cryptic. It’s probably inevitable with cds that in some cases the solver will immediately see the “real” cryptic meaning without being fooled by the surface. But in this case, I can’t even see what deceptive garden path Chandler was trying to lead me up.
Others have been more subtle with their comments but I also thought this was definitely too hard for a Quiptic. That doesn’t mean it wasn’t a good puzzle. I enjoyed it just as much as the significantly easier Monday cryptic.
Thank you C&S
Midge Ure means nothing to me
Never a quiptic
So sad. One clue off from a first complete solve unaided. I’ll get you next time gadget ….
Loved this (maybe just because I was on the right wavelength as opposed to other weeks where I’m well wide)
Thanks both
Not getting to the Quiptic until Wednesday means that no one will read this comment. But it’s been that kind of week. Another who had never heard of Midge Ure, who got distracted by EG meaning “say” in LEGAL EAGLE, and who thought PICKETING was not cryptic in any way. Also had never heard of The Dandy. One day I’ll remember permanently that “on” = “leg,” but that day was not today.
sschua, not to criticize, but those burritos look very……British. [There’s a lot of debate about how there came to be a food called a little donkey (which is what “burrito” translates as), and there doesn’t seem to be a clear answer.]
Don’t know if Bodycheetah is being literal but if cryptic, it’s a fine joke that I very much enjoyed!
Explaining Bodycheetah’s comment: https://www.youtube.com/watch?v=EagwYm8ZmiI&t=180s
Where does LEG come from in 22a??
Too late to be read, but BodyCheetah has a superb wit! Oh, Vienna!
