And Allan, I know this is being very picky, and I am really sorry, but it is Blue PeteR not Blue Pete. If you went into a pub and started chatting to a regular at the bar and commented that the painting that the landlords wife had just hung up looked like it had just been made on Blue PETE you would get blank looks. If you said Blue Peter you would bring the house down and the Landlord would probably buy you a pint for agreeing with him!! :-) I now officially confirm that you are studying at advanced level !! (Nice to see you in Banbury by the way.)
