Hi Susan,
No problem. I don't remember the B & A thing, but sadly these days my not remembering something and whether it happened have an ever-more tenuous relationship. Ah well.
Thank you. As the B and A one was not easy, I thought it was quite allowable to look up brad = nail.

The L from 19 (not 17) down which I wrongly numbered) comes from REHEARSALS for:

The plural worried me a bit - it should be singular, shouldn't it, but the E, H, A R are right - unless you say they are not!
Yes or no would be helpful, as I'll plod on a bit further to see if I can get the answers.
ETA the last four letters of Angelina form nail, but I can't see the reason.
