Many thanks to all you clever people for those answers. That leaves me with just:

23a: Public register's showing bounder among the stars, c-dastral (9)

Can you help me complete it! Thanks again.

Brilliant - many thanks, JCL53 for enabling me to complete the crossword. I should have got composer, but I've never heard of the word 'cadastral'.
