was michael at the O2... he was acting odd because he knows somwthing that we don´t, like billie jean first performance at motown aniversary... at the O2 he sais:
this is it, this is the final courtain call... this is it, and when i say this is it, this is it... because...he knows that was the last public performance before... and all the media will be searching for his last performance before his "dead", and this would be his last... the hoax starts, and he know it!
and don´t worry about all the world talking about his dead, this is normal, not all the world knows about the hoax!
