Thanks once again for all your help folks, I still have eight to solve and the closing date is fast approaching.
One I have only just noticed is the number 1, "Obscure poet holds nothing to write on" I can't recall seeing any additional clues for this one.
The others I need are 10 35 41 49 62 79 and 86.
I will be posting my entry in the next week or so even if I get no further.
Good luck to everyone - I am looking forward to the next Rainbow Quiz when we can all start again
