was it all a dream?....

You know when you have days when you look back and wonder if it really happened at all? well today is certainly one of those days for me.
I think I have returned from a two day conference in Hereford where yesterday I think realy did happen, but looking back on today I am not sure if it has happened yet... did Jon sing 'you sexy thing' in front of a chanting crowd?... why are some conversations a blur? what was said? hmmmm... my head is very confused... answers on a postcard please...
