My favourites were 9a and 10d.
I could not pass 26 apart from EGO.
Thanks Peter and Everyman – this was a very enjoyable puzzle
Thank you, PeterO, I needed your explanations for parsing 26 and 27.
Some of the parsing was intricate at times, but all perfectly gettable. Overall about par for Everyman, and as enjoyable as ever.
Thank you Everyman and PeterO.
Good fun as usual – let alone a “hard thing to say”, TONGUE TWISTER was hard to parse…
Very difficult for me but I expect some will say it was easy. I was looking for a verb for 18ac – not a noun so put theatricalise, which didn’t work. Don’t like the parsing. Peter O I think theatrically has two l’s.
Liked 24 ac but there were many I couldn’t parse in this one. Not as enjoyable today as some recently.
no not easy for this solver! A few were straightforward but I was looking forward to the explanations as I couldn’t work them out
I found 15ac 18ac 3d a bit round about
but liked it overall…
Wow! Two &lits in one crossword?! Even the humble Everyman surprises. Bravo Everyman, bravo!
A very enjoyable crossword with too many good clues to mention them all. Thanks Everyman and PeterO for the parsing.

Indeed the word is theatrically; but I was not intending to say that the one-l version was a word, but an anagram (ok, that might suggest that the result is a word, but not always so in cryptics, where a word answer may be cobbled together from parts that are not necessarily whole words) of ‘act heartily’, which, with the inserted ‘it’, does form the answer, a word correctly spelled.
Very nice puzzle. Struggled, but got it all out, *including* all of the parsings!
Got stuck for a long while on 15 across, because I was sure that it was an anagram of “Certain tin once” and that “fixed” was the literal meaning. Finally I realised that “Certain tin once” has *14* letters, not 13. Duhhh. There are three sorts of people: those who can count and those who can’t.
