This'll totally give away where I grew up, but
There was a woman in my home town known by the locals as Karaoke Karen who would regularly go to the town centre with a stereo and just start dancing in front of everyone shopping. At the time it was quite odd and rather random as to when she'd do it. As I've grown up I've actually grown quite jealous, I wish I was self confident and just didn't care what other people thought enough to start dancing away. There are enough nutters in my home town without adding another one in though!

Length? Roughly 3-5 minutes per song.

EDIT: Just found a video on youtube: www.youtube.com/watch?v=PLPe1grstCM

There's a facebook group if you look hard enough. Hope you made it out too.

I did also make it out, it's depressing the number who don't. First Brighton, now Cambridge, I'm doing well! Yourself?

Sometimes...
you just gotta dance like there's no-one watching.
