Thanks brendan as usual, and mprs too, ha-ha!
Right the weekend is nearly over and I'm not getting this despite what looks like an almost full grid, so desperately need gentle tips for my remaining Ring clues 33 and 37; and Radials 2, 10, 17 and 24.
Or some of those! Enough to reveal the inner circle. Someone said they got the theme from 12 and 13???
I am on night shift, so need to crack this. I see you are a night person Brendan - last night at least!
