It was the orange clue that provided the key. I listen to the radio a lot, so it was easily recognisable.
NB to all the rest of you. This will only be the key if you're British --- for Americans this is a really tough clue, and you should start somewhere else.
As for the rest, the only ones I am unable to solve are clues 2,3,4 and 5.
Once you've got 4, 2 and 3 will follow.
5 is, I think, the one of the most ingenious clues of all, but not necessarily the most difficult.
No and it's driving me crazy!
It should take you slightly less than an hour if you're uninterrupted.
That was a clue, but not a very helpful one.
You
will know when you've got it.
