Thanks for the answers to nos. 99 and 100. The answer to no.91 isn't quite right as the question is "Folk-rock singers/song writers" and the answer is 3 words(5,3,9) Any more ideas?
Mamylymnne's clue was excellent- good idea to give clues instead of answers and most of M's clues are really good. I've to stop myself from answering !!
