Watch Sara Bareilles + Straight No Chaser Record ‘I Want You Back’ in the Studio [Exclusive Video]

Ten-man a cappella group Straight No Chaser joined up with Sara Bareilles for a cover of the Jackson 5 classic 'I Want You Back,' and you can watch footage from the recording session exclusively here on PopCrush.

The video clip gives viewers a chance to hear a portion of the track and see how the singers came together in the studio, goofing off and having a good time between takes. Bareilles sings lead on the track, with Straight No Chaser providing backup vocals in place of instruments.

At one point, Bareilles, who has scored solo hits like 'Love Song' and 'King of Anything,' finds herself surrounded by the guys, who all have their cell phones out trying to record her as she sings. Bareilles ends the video by jokingly declaring, "I am really looking forward to leaving. They're abusive in a lot of ways, which is kind of disappointing, because they seem like really nice guys."

'I Want You Back' is the first single from SNC's latest album 'Under the Influence,' which arrives on May 7 and also features collaborations with Jason Mraz, Seal, Rob Thomas, Phil Collins and Dolly Parton.

Straight No Chaser formed in 1996 and disbanded a few years later before YouTube footage of their old performances went viral and prompted them to reunite. Energized by their new online fame, they went on to release three successful albums (so far) and will be the subject of an upcoming major motion picture from Dreamworks.

Bareilles is planning to release a new album of her own later this year as the follow-up to her 2010 chart topper, 'Kaleidoscope Heart.'
