Cheers guys, the families are quite conservative / religeous, so i have been warned to steer clear of a lot of the funny but dodgy stories i have.
I also havent seen loads of him in the most recent times and so fresh content is thin, its made doing the speech quite difficult but i think i have cobbled something together that will do the job.
I've got the nerves aswell, but as you say, they will pass once it starts im sure, im going to go away tonight and have another really good thnik about funny times and see what i can cook up.
