One night after releasing the song "Get Lucky" with Daft Punk, Pharrell performed the song live (well... he sang live, accompanied by a backing track) at Brooklyn's House of Vans during a promotional launch event for HTC One.
The memorable part of this performance is that Pharrell does the song 3 times! The third time through, he gets the crowd to sing along. It's fair to say the song is an instant classic.
