A little before 9pm on Wednesday night and I'm standing on the 'VIP' balcony of San Francisco's Regency Ballroom, holding a can of something called 'MySpace Buzz' and waiting for Weezer to take to the stage. It's a weird scene, all told, and not just because I thought Weezer was dead. The bulk of the weirdness stems from the make-up of the crowd: a dozen feet below me in the main auditorium there are maybe a couple of thousand writhing teenagers - Weezer fans to a (wo)man, cheering and shouting and jumping and sweating and doing all the things I remember doing a little over a decade ago. These are the invited fans; those lucky enough to have been chosen to attend this 'secret show', organised by MySpace.
