This would have been so much easier if I'd actually noticed the special instruction from Philistine!
Every now and then I'd come across a clue where the wordplay clearly led to a specific answer, but I couldn't see a definition. After this happened for the third time I thought "something's going on here" - and indeed something was.
Other than that, there's lot to like here with some quite brilliant clues - 12a, 17,20a, 19d but my COD is the outstanding 15d Silence ego? (3,7)
I'm still not totally sure of 24a where I can't marry (geddit?) the answer with the clue.
Thanks to Philistine for a clever and witty crossword.
Stay safe:-)
