Cryptic crossword No 3,445

Fun start to the day, 10a 17a and and particularly 21a were favourites. Got there with word play, but I felt definition for 15d etc was a bit too loose to be fair.

Thanks Ubu. Enjoyed this. Great humour and good clues - I particularly liked 17a, 3d, 16d and 27d. 15a etc doesn't pass the fairness test for me either - the definition is too loose and some of the references in the clue are too broad/obscure.
