I've astonished myself by practically finishing. I only have the second word of 5d to get for which I have ?A?T. This assumes my first word is right. I think I've been having a mental lapse. Please can I have a hint.
I did have trouble parsing a couple including the first four letters of 10ac and 16d. Not to mention 24d. I got 1d (nattily) and 25ac once I spelt it right.
I actually found this crossword easy. I seemed to be on the right wavelength with Paul for once. I enjoyed the long clue and there were several anagrams and hiddens for me.
I mentioned far above that 17 was familiar...it occurred in the wordplay of the very recent Guardian Prize 28,554 (Picaroon), and as a solution in Paul's Guardian 26,207 (2014). Not surprisingly, Cyclops in Private Eye has also employed it.
10A is 2 homophones following each other
16D is a word for "with", followed by the first letter of 2 other words inside a word meaning "standard"
24D is 2 words meaning 1 dollar truncated and reversed
I recall Enigmatist's one-time record (based on Roger Miller's "King of the Road" (even solved it iirc), but don't know of Taupi's magnum opus involving the first paragraph of "Catch-22".
