Have now got those two. 2d had been confused by the fact that I had not put a pair for 12a, just the original word! 10a took a while as was using a slightly wrong word for limit. Now need 18d and 23a. Any clues?
Thanks, xwordfan, but, although 10A was the second clue I solved, I got a four-word musical term (amongst other meanings) for which I still can't find a pair.
Thank you. Had spelt 23d wrong! I think I have finished though not quite sorted out why I have the answer for 25d that I have got. Really is time to do some work now!!
