Jude Law’s earned a reputation for being a bit of a grumpy pants, so seeing him doing karaoke in a bar, out in public, is a bit of a surprise. In fact, we probably wouldn’t have believed it had actually ever happened if we hadn’t seen this video with our very own eyes. Jude let his hair down and sang a rendition of Chuck Berry’s Johnny B Goode with a pal - and he’s actually not that bad. We’re not saying he should give up the acting career to become a rock star or anything, but he certainly had the audience clapping and cheering.
