Tyson Fury and Deontay Wilder square up at the Staples Centre in Los Angeles on December 1 in what is sure to be a blockbuster fight.The rejuvenated Fury, after spending the best part of two years away from the ring suffering from alcohol and drug abuse, is ready for his biggest fight since defeating Wladimir Klitschko way back in November 2015. On the other side of the ring, Deontay Wilder is in the form of his life and has been regarded as one of boxing's finest for a few years now, undefeated in his 40 professional fights.This is sure to be an unmissable fight for so many reasons. What no-one really expected to see in the build up to the fight was the two men sat on the same sofa, posing for the cameras before going on stage. A video has emerged of the two men laughing and joking (more-so Tyson Fury) while sat on the same sofa, posing for cameras from BT Sport. We can see in the video Tyson Fury sharing some laughs with the production crew, asking, "What's he (Wilder) doing in my changing room?" before going on to say, "You know we're big time right?!" in wondering why the two are having to pose next to each other on the sofa.In fact, Wilder stays completely silent in front of the cameras, perhaps a little bewildered by Fury's comedic behaviour. 

What no-one expected from this behind the scenes look on the two sitting side by side was Fury going on to ask Wilder, "Let's do a duet, Let's do a duet!" 

We then see Fury start singing 'A change is gonna come' by Sam Cooke while Wilder still silent, but perhaps a little more uncomfortable now that Fury is singing to him. 

While this was a bizarre insight into what the two got up to behind the scenes, everybody will have eyes firmly set when the two heavyweights get in the ring and battle it out in front of a global audience in December.
