SK, that sounds great! I usually groan when someone says "we're going to play a game", but then really get into it. Yours sounds very fun, and will, no doubt, be the highlight of the conference for many!

And yes, I have that song in my head, too. But that's OK. It drove out, temporarily, "Strangers in the Night", which often plays on a continuous loop in my head. Especially at work.
