Just one clue left to get - 27D - not a word in the BRB iPhone app. I have an answer in mind, but if it is right, I don't understand the wordplay.
Really enjoyed this one, although 13A, 29A, 32D and 19A all took an age to solve (the last not helped by me having originally got the first letter of 20D wrong!). Can't fault the clues though, I just wasn't on the right wavelength!
An excellent endgame; I was on the right lines from the hint but it took a little while to get exactly the right interpretation; once the first suggestion fell into place, the rest followed pretty quickly and allowed some reverse engineering of a couple of the more recalcitrant clues.
Now off to look at 4201 - although from the comments on here it sounds like a real mind-bender!
