We lost one of the greats on Monday when Robin Williams died. You all know he could act and make you laugh. But did you know he could sing?

And did you know that he sang The Beatles? It did happen and the recording is on YouTube.

In 1998, Williams collaborated with singer Bobby McFerrin, of "Don't Worry, Be Happy" fame, on a version of "Come Together" that appeared on a now-obscure tribute album to the Fab Four's producer, George Martin. The record, which was titled In My Life, also features such celebs as Goldie Hawn, Jim Carrey and Sean Connery interpreting Beatles and other Martin-produced classics.

Yep, Robin Williams could sing, too. Hear for yourself.
