Sounds like an awesome gig!

I've seen the the Flaming Lips live 3 times myself and yes, they always put on a show. Waitin' for Superman is one of my favourite tracks. I'll be listening to that in the car on the way to work now...

One of the best live performances I remember from them was the track 'A spoonful weighs a ton' which as well as it's deep base line also features the Teletubbies. At the point the base kicked in they dropped a load inflated balls from the ceiling (no one was inside these ones) while on stage they had a load people dressed as animals dancing around on account of the Super Fury Animals having played as their support act. The place went wild!
