Agreed on Brendan's parsing of 1a, though frankly I don't know the personage / celebrity involved.
Pretty good puzzle, thanks to Everyman. Quick solve, but some clues had complex parsing and took significant thought.
FOI 1d, LOI 16.
Favo(u)rite clues 23, 9 and 21, though 3 must be praised for potential geek connection.
Thanks to edc for starting the thread. Apologies for a bit of pedantry: it took me a long time to become aware of the custom, but Everyman thread titles here dispense with the comma in the puzzle number. [Yes, I started at least one Everyman thread with a comma in the title...😳]
