An intriguing puzzle, and not straightforward even knowing the thematic material. Some tricky clues, and there are just a few I can’t quite crack fully.
I don’t quite see the definition for 27, “Treatment of bullies cutting boy’s face”, how it fits the clear answer. And I can’t quite figure the wordplay for 3, “Small flap on instrument in the box close to exit”, and 35, “Shut up on stage, retiring on Duke’s exit”. If anyone can just nudge me to the finishing line with those it would be much appreciated.
