One of the guests and speakers at the event was Gerald Ratner the (in)famous businessman now turned public speaker. He gave an excellent and entertaining presentation on the joys and pitfalls of business. I was lucky enough to grab some of his time afterwards, had a bit of a chat and showed him some card magic.
All-in-all it was a great event and many thanks to YELL for inviting me along. If you've got a forthcoming event that would benefit from a bit of magic then get touch!
