VIDEO: Jay Leno Karaoke Prank Goes Viral

We’ll be honest, if Tubs appeared on a screen at a petrol station while we were filling our car and asked us to sing karaoke in front of a huge audience on The Late Late Show, we’d probably tell him where to go.

But when Jack Rafferty off The Tonight Show with Jay Leno did it to a man in America, he was more than game.

In fact he gave his all to his rendition of Bon Jovi’s Living On a Prayer before his other half got out of the car and sang Sweet Dreams by the Eurythmics.

As well as the millions of people who would have been watching the show, over 800,000 people have viewed the clip on YouTube.
