WATCH: Arcade Fire's Win Butler Sings His Own Song at Karaoke

Win Butler had a busy week. He helped lead his team to victory during the NBA All Star Celebrity game, and he sang his own song at karaoke.

On Friday, Butler surprised fans in LA with an impromptu karaoke performance of the band’s 2007 song “Intervention”. He hung out for a while following the song, taking pictures and chatting with fans.

So, uh, Win Butler just casually dropped by some karaoke spot in Little Tokyo (Los Angeles) last night. I'm guessing he maybe noticed they had "Intervention" on their repertoire and couldn't resist, or something.
