Aaaaarrrrgggghhh. Can't make it. I am on the organising committee for son's school Christmas fayre which is that day. Have already ducked out of helping at another event this Thursday (going to Top Gear live) so cannot duck out of this one too.

Aaaaaaarrrrggghhh.
If date changes (saturday? Or following weekend?) then am in but otherwise will have to be next time.
