I've put thirty years effort and time into preparing the lessons I teach now! Off the cuff they may be, brilliant they sometimes are, but unprepared - never. I don't use a crib sheet in school either!

As to the kick him in the gooloies comment - it will be SJ who says it and he's bigger than me (but I know he doesn't mean it!)

By the way SJ, performing as a duo is more than half and half - the two brains need to be in communication as well which can be tricky. But then, thats another thing thats had thirty years plus preparation.....
