Billie Joe Armstrong has, rather sweetly, tried to stop people filming Pinhead Gunpowder gigs and putting them on YouTube. Well, it doesn't hurt to ask, does it?:
We're not sure that it actually wipes memories out of people's brains if things appear on YouTube - does it work like that?
We know, of course, that Billie Joe begged for fans to put their cameras away, thanks to the large number of people who filmed him saying this.
