Roger Federer’s talent does not only extend to playing tennis.

The 18-times Grand Slam champion showed he is also on song off the court as he teamed up with fellow players Tommy Haas and Grigor Dimitrov to deliver a unique rendition of Chicago’s Hard to Say I’m Sorry with David Foster, father-in-law of Haas, playing piano during a break at Indian Wells.

Look out for a hilarious Novak Djokovic ‘videobomb’ halfway through the tune. The Djoker is never one to take a backseat.

“I actually didn’t know the lyrics very well, so we were reading on the iPhone. And next thing you know, it’s like, this is too funny not to put it on social media,” said Federer. “So we put it out there. People had a blast over it, laughed at us, and I thought it was great.

“As we regrouped here, we thought we could do it again, but this time kind of on a playback, making the boys actually sound nice and not like cats and dogs singing, like in Australia.

“Now it sounds somewhat okay. It’s still so bad, yet I think it’s actually so good.”

It is an idea that has already been picked up on on golf. Here are top US players Bubba Watson, Hunter Mahan, Ricky Fowler and Ben Crane showing their quality as the Golf Boys a few years back.
