As we remember the late Robin Williams, there was a time when he sang The Beatles. Yep, it happened and the recording is on YouTube.
In 1998, Williams collaborated with Bobby McFerrin (of "Don't Worry, Be Happy" fame) on a version of The Beatles classic "Come Together" that appeared on an obscure tribute album to the Fab Four's producer George Martin.
The record was titled In My Life. It also featured celebs Goldie Hawn, Jim Carrey and Sean Connery interpreting Beatles and other Martin-produced classics. Take a listen: (Source: Faster Louder)
