Thanks to Brockwell (responsible for the excellent Bob Marley Catch a Fire puzzle), for this very well clued and themed Prize puzzle.
The surfaces were so smooth which, given the complications posed by the theme, is no small feat.
If you do get stuck, there are at least two long anagrams, both in the downs.
I had to Google the answer to 3d to see how it related to Mr Murdoch and 20d was new to me but, other than that, I had no real problems.
So many potential CODs but, if I had to pick one, it would probably be the wonderful 27a... or 20d... or 7d... etc., etc.,
Thanks again to Brockwell for this wonderful puzzle.
Stay safe:-)
