Well I've been staring at this for a couple of days and I just don't see it! Possibly not helped by not getting 10d. Worn-out singing voice in "Grease" outwardly yielding bass and tenor. I want to say "breast" from the wordplay (b-reas-t) but don't see what that has to do with a singing voice. I have bar-s- as the entry.
I can make a word c---t, after the starting "a thin", which gives a 6 letter word starting with g in Bradfords that happens to be an anagram of the finishing "ring" an two adjoining letters. Am I on the right track? I can see several possible words in the grid but none that seem to complete the circle.
Can anyone give me a nudge please?
