As others have said there were some easy clues for Paul, so I almost finished this with no external help - which is rare for me with a Paul crossword.
My lack of classical knowledge stumped me for 14d / 17a. For 14d, I spotted the device, but didn't realise it gave me a valid answer. And the only 4 letter composer that I knew starting with the correct letter was wrong :-(
For 4d I think I've got the answer but can't parse it. I can get an "endless fruit" for the 1st 2 letters, but stumped by the rest (unless its a 5-letter curry followed by the starting letter of another word in the clue.
