Ok so it's on at the Bridge. I'm not quite sure what's exactly happening but here's what I know.

Mr Wizard, Rosie, Theo and yours truly will be at the bridge, playing some stuff, for a bit, in the bar. 

Dragon's on in the next room at the same time.

Umm...

That's all I got :-) We'll be there, if you;re a mate of Judes, come join the chaos.

She'd approve.
