I have a private booking on Sunday to perform magic to a very posh house, and I am pretty sure the guests are going to be quite well off and very well educated. I will obviously be dressing the part and astonishing my audience as normal, and will be handing out my business cards. I have also got my own private photographer with me to take some snaps of me in action. I am just 'paranoid' and just making sure everything goes right! - I have a few more days to think, my magic is up to scratch, and my performance is fine. I am just thinking of last minute checks which I may need to check just in case! Any things I should think of? Or anything I may of forgotten?
