Pharrell Williams new song, 'Happy," has quickly earwormed its way into people's hearts. Check out this performance of the song by Gillian Cosgriff in Melbourne, Australia. She played on a street piano that is part of a project called 'Play Me, I'm Yours.'

This video was made at the National Gallery of Victoria. The 'Play Me, I'm Yours' campaign places pianos, decorated by local artists, all over the place for people to play and enjoy. (Sounds very similar to Fort Collins' 'Pianos About Town'.)

They showcased the program with this performance by Gillian Cosgriff, Sage Douglas, Josie Lane and Robert Tripolino.

Yes, the video looks to be staged and not a complete impromptu performance, but that doesn't change the fact that was an amazing performance.

Gillian had this to say about the performance on Facebook:

Today's #streetpianosmelb song is HAPPY! (That's the title mates.) It's a cover of Happy by Pharrell Williams!

Feat. the brilliant Sage Douglas, Josie Lane, and Robert Tripolino on back up, and filmed by the excellent Dave Zwolenski and Matt Saraceni. This is the MOST fun I've ever had at the Arts Centre Melbourne . And that's saying something, because I've had a lot of REALLY fun times there.
