Well this was a struggle, and I needed quite a few pointers but I enjoyed it very much. Thanks Paul and of course thanks to all contributors here.
FOI 10a, LOI 12a because of being stupid, cod probably 22d but 6d and others are good too.
Chrise, I must take issue with your question mark after 'music' @46- definitely a distinct, honourable and enjoyable genre. I also think the artist is well enough known for the I or e ambiguity to be ok, but my daughter-in-law is the artist's compatriot so maybe that counts as specialist knowledge.
I think I only knew 22a because I spent my sixth form in a half-boarding school in Keswick, but had little problem with that or 22d .
Now to wrestle with the maddening Captcha, then on to Everyman!
