Well I missed the big G8 concerts. I also missed LiveAid and FarmAid and the rest. i had a chance to go to FarmAid I or II or maybe it was III, it is just not clear to me anymore, 'cause I don't care. I love Pink Floyd, but I do not want to be lectured by a musician or a movie star. I am pretty sure I am smarter than 99% of these people, and I do not need their advise. Why is it that just because you were in a movie you become an expert? Anyway read this guy, he explains it as well as possible.
