I can't a thread like this hasn't been started before! Great idea. Can you keep updating the OP with the list of names you have so we have a definitive place to look. It would be better if you could give peoples names (rather than "my Mum") and where they are sitting so that we can all introduce ourselves to to each other properly.
By the way, I hope to be going but as I am on crutches I need somebody to stand behind me to stop me toppling back down the concrete steps if things go awry. If any one wants to volunteer it would be really great.
