Just a few left. Any hints appreciated!
11d
28ac (I can find only one word to fit, but doesn't seem to have anything to do with the clue)
39ac (first word looks fairly certain, but I can't find anything to follow it)
54ac
Thanks, syzygy - I had never heard of that (how did you come across it?)
As I haven't replied to one of my posts (yet), I hadn't realised I am recapitalised. I did notice that AB was, though!
