re: Have any of you ever been in the audience of a late night talk show?

Was never in the audience, but I watched the band for the Arsenio Hall Show rehearsing with a new member in the studio during a Paramount tour. We clapped when they stopped playing while we ere there.

We also went in a big prop warehouse where we touched the knife from The Golden Child, the rabbit that got boiled from Fatal Attraction, and ice cubes from a Cheers set they had set up in the room. We got caught sitting in the chairs on the bridge on the set for one of the Star Trek movies. Found out afterwards the tour guide wasn't supposed to have taken us down the aisles of the warehouse or in the set for Star Trek.
