They're live right now on Youtube's Coachella streaming: http://www.youtube.com/coachella
AND OMFG i get a chance to... well starting from the beggining... someone from the crew has spotted Win wandering around and they were like: 'look at the right' and there he was, and i just spontaniously waved to him and HE CAME TO US!
he shaked my hand and we had a little chat, but i couldn't say a word except for ' my heart is beating so fast right know' , ' i'm so stressed out' bla bla and i made such a dumba** of myself but when i said that my English fails he said it is really good, and he was so nice, all smilling and so!
i wanted to ask for a picture, i even had my phone in hand, but somehow i was afraid of, don't know why... 
and i was waiting for William to start running and jumping on the stage, and he was so into it that he lost his stick
never forget this concert! 
It's disco-tastic!
