There are a lot of hallway jams, but I don't know if they're tough about wristbands (I've never joined the jams, just listened). I've seen a lot of men in swirly skirts there. You might recognize some dancers/musicians from the DC area -- I often see somewhat familiar contra dancers, for example -- and from the Boston area. I don't know who for sure, though. The only person I know going for sure is a singer from NYC.
