Hi
I was wondering if anyone could tell me what they're saying in this clip : http://www.youtube.com/watch?v=ewFTTEibJdU

it's a clip where Tegoshi and some other people (would like to know who if possible) showed up in the audience of an Arashi concert (hehe they went to watch their sempai!) and Arashi are all really surprise to see them and everyone goes hyper ^^;;;

I'd really appreciate if anyone can do a rough translation of it (no need to eb afull one ^^)

thanks in advance!!
