A fine Quiptic from Budmo, which I fancy will appeal to newer and improving solvers.

Many thanks to Budmo for this week’s Quiptic.

I did not fully parse 8d.
New for me: BACS = Bankers’ Automated Clearing Services (for 10ac).
A little extra context for 27d
https://en.wikipedia.org/wiki/Back_to_Life_(However_Do_You_Want_Me)
Thanks for the blog! In 25a, I think that the part of the clue that should be underlined is “like a devil”.
Thanks, majortom. Corrected.
Quipticky in general, but with some obscurities, for me at least; some were guesses. Not sure about the definition of PERSONNEL (should “in” be included, maybe? and even so) and where A comes from in A FAST BUCK. DOWNS is a great clue, as is LANDGRAB. Thanks Budmo and Pierre!
Thank you Pierre. Great blog as always. I wondered how accessible was the A >per (each) in the clue for PERSONNEL, but you’ve spelt that out. It’s been commented on in the full strength cryptics, where, even knowing the trick, it’s often missed. Nicely disguised too, as it’s the first letter and capitalised.
I had a sense there may be a fairly pervasive political theme, but it was probably just my horror reading the news before the crossword came up and maybe I’m reading too much into things.
My favourites were FATHOM, MARIE OSMOND, BASICS, ANG LEE, and GANGES (thanks to a comment by Ramanath on the G site).
I’m not a new solver, Pierre, and I doubt I’m an improving one – but this quiptic appealed to me, too.
The surfaces for GANGES, REARRANGER and PRONTO made me smile – and the anagrams for FIRE STATION and MARIE OSMOND were pleasing. (My partner complained that the latter was pretty obscure: that’s the trouble with GK, isn’t it – you either know it or you don’t.)
FATHOM and LIBRARIAN were my favourites
Thank you Pierre and Budmo.
Solid and set at a nice level. 27d was good fun and will have me humming Back to Life for the rest of the day.
“Marmoset” always makes me think of the phrase to craunch the marmoset from the flamboyantly substandard phrasebook English As She is Spoke which I was made aware of my Stephen Pile’s 1979 The Book of Heroic Failures.
A very approachable crossword. Thanks Budmo and Pierre.
I enjoyed this. A bit of disappointment at the repeat of AIR near to REPAIR, but really that’s nitpicking.
As a newish solver, I found this to be mostly at a good level and was very amused by the “Back to Life” clue. I was particularly pleased to get CAVALCADE – I found that a very satisfying process! My LOI was FATHOM. I had no clue a fathom was 6 ft. Overall, a fun puzzle.
Thanks for the blog, Pierre!
A very nice Quiptic, as long as you know all about BACS, FATHOMS and MARIE OSMOND!
Comment #13
Very enjoyable and spot on for the Quiptic slot I felt. Steady progress made top to bottom. Lots to like: CAVALCADE being one of my favourites, and 8d MARIE OSMOND where the surface is perfect in terms of its reading and answer IMO. Thanks Budmo, and Pierre.
I was watching a Soul II Soul video of this last night in a friend’s house, saying how much I adored the song, so this was a pleasant coincidence. I liked FIRE STATION, CAVALCADE and thought MARIE OSMOND was a great clue and I must confess to a teenage crush, while all the girls at school were fawning over Donny and David Cassidy. Excellent Quiptic.
Ta Budmo & Pierre.
