Bands that got the Y-front treatment at Greenbelt included Why? (we loved Why?, cheerful, bouncy music and the people in the band were really nice, enjoyed talking to them), Griff Pilchard, Eden Burning
We were supposed to be taking our giant Y-fronts flag onto the main stage on the last night during some of the bands but the security guards wouldn't let us. Never mind, there's always next year.

My tent at Greenbelt 96 wrapped in purple bubblewrap to make it better insulated, more waterproof, and ... err ... more groovy?
