Dear Cher
Dudley knows bugger all about anything much really, so you'll have to give him time to look it all up on the internet before you get an answer on this one.
BTW he is presently in a curry house eating "After Eights". Do you have those in America? They are delicious little plain chocolate squares filled with mint cream. (I know this because Martin is with him and I have just spoken to them both - I am at home in Devon having just returned from a barn dance in Mamhead Village Hall and it was the best fun I've had in ages. I mean that's why I know he's eating After Eights, not what they are made of. Sorry but I've just drunk a large Cointreau and it's gone straight to my head).
Note for Dave .... the stars are great here tonight. I've just been out in the garden and it's really clear and I just saw a shooting star, and Mars is still pretty good too.
Mmmm, time for another Cointreau I think.
