The Hangover is quickly becoming one of the most anticipated comedies of the summer. With a cast that includes the likes of Zach Galifinakis, Bradley Cooper and even Mike Tyson, the story of four guys in search of their buddy after a rockin’ bachelor party has just about everyone singing In The Air Tonight.

This new trailer features Cast member Ed Helms, who you may recognize from NBC’s The Office, singing a special little tune about his friends.
