Pharrell’s album G I R L was unleashed on the world this week via an iTunes stream (it officially comes out tomorrow), and his song “Happy” is currently holding the No. 1 spot on the Billboard Hot 100. The track appears in the Despicable Me 2 movie soundtrack, so the timing was perfect for Pharrell to make an appearance at the 2014 Oscars tonight in Hollywood. He took “Happy” to the stage with plenty of company, got some front row guests to join him in dance, and, of course, he brought out an awesome big hat.

UPDATE: Watch Karen O (from Yeah Yeah Yeahs) and Ezra Koenig (Vampire Weekend) perform “The Moon Song” from the movie Her below.
