ixion, it sounds like you've finished, so can you tell me if I've got the right letters in 15D, please?
-U---P-I-
I thought it was an anagram of 'euphoric' for 'passionate', plus 1 letter; but I can't parse the rest of the clue.
Originally I also had a C as the 4th, i.e.
-U-C-P-I-
but I wasn't sure about my answer for 20A as it makes the clue rude enough to be one of Paul's. Does it have a P added to it?
Am stuck for the moment, about half done.
