Not being part of the early brigade, I benefited from the hints about 3d in this week's posts and this unlocked the rest for me (eventually). A testing crossword with more complex parsing. Satisfying, nevertheless, with 17a my COD.
When I started doing Everyman in the '60s, I had to wait until the following week to fill in the gaps and then work out the wordplay and parsing (as well as learn some new words and usage!). Thanks Everyman and fellow posters.
