Sara Bareilles ‘Uncharted’ Video Outtakes Include Adam Levine, Pharrell + More

Sara Bareilles' 'Uncharted' video has been one of our favorite music videos of 2011, and considering it was done via webcam, using music stars who are not Sara Bareilles, it seemed virtually flawless to the untrained eye. But in fact, behind the scenes it wasn't as smooth as it appears -- and this outtakes video proves it.

Apparently, Pharrell, Tegan and Sara, Ben Folds, Sugarland's Jennifer Nettles, Vanessa Carlton and 'The Voice' coach/Maroon5 frontman Adam Levine didn't know the words to 'Uncharted' when they agreed to star in the video in place of Miss Bareilles. That's okay by us, simply because it makes for an additional hilarious video!

And while he's not a celebrity in the traditional sense, funny guy Keenan Cahill appears to be the only one who truly did his homework. Is it cheating if he lip-syncs other people's songs on YouTube for a living? We think not.
