Ixion - given you've used my answer for 'R', albeit in the plural, I guess we have different answers (unless you're being nicely subtle) - my take is that the last 5 letters of the answer are simply a synonym for 'L' - assuming my 'L' is correct of course.
Hope that makes sense!
RH side complete but upper LH side looking a bit sad. I could do with a hint for the other 15. I've got the seventh I bit I think but no idea what to do with it. Also, if it's not giving too much away does F go at 2dn?
No to the F question (sorry). Don't understand why you don't know what to do with the "seventh I" bit..... Do you mean the 10,5? Happy to give clues. Which would help most?
Simondx, ok, does F go at 1ac? If not bottom left will need to be erased. Yes, I meant the 10,5, misspelling one, I've got some letters in but don't know what I'm looking for. Please don't let it be Harry Potter!
teenieleekie - in case Simondx doesn't see your post for a while.
The 10,5 begins with 'B' and the other 14 letters are an anagram of letters in the clue. The definition is 'work' and a very famous (musical) one at that - definitely not Harry Potter.
