Ahhh, I know what you mean.
We had the Woodford Folk Festival here over New Years.

We could hear the music from our place. It rained for practically the entire time the Festival was on. So they were very clean Hippies.
Probably the same crowd has turned up at this event.
They're "Mostly Harmless". Enjoy the floor show.
