I have done all of that - I know the 6 unclued answers. Trying to find diminutive for our late Queen (if it was from My Fair Lady I could see it). I must be particularly obtuse today.
Sorry, teebee. I must have just been lucky with filling in the row, what was needed seemed to just jump out at me. (And we had the Jubilee Line only a few weeks ago, that maybe helped).
