Hi chrisg,
You've probably got the answer to 22a by now, but just in case you haven't, it's actually easier than you (and I, at first) think.
You need to split the clue into 2 parts (as there are only 3 words, no prob!) one part is a dictionary definition of the word, the other, a fairly well known person, the answer, of course, is the same for both.
Bet you a £ to a penny that you get it!
