Quickest ever for me, I think. I'm also a teensy bit insecure about the unch in 25d because of obscure parsing, and while confident of the answers, don't quite get the wordplay in 12d, 44a -what happened to poor dismembered Rosalind?
I too loved 18d. Ozymandias.
Thank you, Llig - not insultingly easy, ingenious and entertaining.
