First of all, I saw this happen, in person. I also saw the rehearsal.
And then, we ran into him backstage. We was unhappy with the sound mix and informing a staffer about it -- we actually walked in to a tense moment. My eyes got as big as saucers and my voice raised about 25 octaves. Clearly, we were not supposed to interrupt and gush or anything. But since I almost ran smack into him, I squeaked, "Oh, hi!!! Pardon me!!!"
At this point Thor tried to smile, but as he described it, he just kind of wrapped his mouth around his teeth, and his brain sharted.
Then Tom Waits said, "Hi. How ya doin'?" And we scurried away.
My friend is certain that his boss will scold him, because it seemed planned, but it really wasn't.
Considering how we both wanted to throw ourselves at him and proclaim our love, I think we played it pretty cool. Except we were so, so uncool about it.
