Yep, I was there too !
The idiots actually entered the bus but got caught... good thing, since they were so affraid of the guy who was yelling at them that they finally left and we got to enjoy our meeting with Matt without being annoyed...
The dad thing is, they left in a car and I'm pretty sure the driver was drunk as hell. I tried to run and find a police car in the area but too little to late... I can't say I'm actually proud of letting them hit the road like this but on the other hand I was so glad they left...
About the beer flying, I'm pretty sure it was his two moron friends who were standing a little farther from the stage.
Yes, they were quite a trio of ass@#$&...
