Slogged through this one unaided, slow but steady, while on holiday, and enjoyed it. Haven’t come across the theme before, but I’m not one of those who grumbles at unfamiliar theme: part of the joy of these puzzles is to be introduced to new things through the thematic element.
I have just one question mark left on my paper: I can’t figure out the wordplay for 15, “preposterously lend bouncer…”; if anyone can provide a nudge that would be appreciated. And I didn’t get the title either, but thanks drxx for that :-)
