This is just what the doctor ordered, not too heavy and with lots of wit.
FOI was 23a so I did initially think I might struggle but, thankfully, the Everyman usual suspects came to the rescue.
As an East-ender I pretty much despair at the usual
hackneyed (see what I did there 😀) clues that require conforming to some dated stereotype, so I was particularly pleased by 15a and its amusing take on the same theme.
By pure coincidence I am currently reading ABC ...... by 17a (that's amazing Bren, tell us more 🥱Zzzzzz).
19a - I couldn't think of any examples where the answer could be swapped for "proceeding" but it is in Chambers thesaurus so that's good enough for moi:-)
I still haven't parsed 1d and 24a so they'll take a bit more investigation but, other than that, I'm home and hosed.
Stay safe:-)
COD - I really like the charade at 26a and the homophone at 3d but the winner is the aforementioned 15a.
Thanks to Everyman for a fun puzzle:-)
