For Roger Federer and his tennis mates, providing vocals for a Grammy-winning composer now seems to be a hard habit to break.
Nearly two months after the reigning Australian Open champion stunned the world with their impromptu collaboration with music composer David Foster, they're at it again. This time, though, as seen in this video posted on Federer's Twitter on Friday, the newly christened "Backhand Boys" made sure they came up with a winner.
Federer, Foster, Grigor Dimitrov and Tommy Haas reunited to perform a more polished, well-practiced rendition of the 1980s classic "Hard to Say I'm Sorry" by the band Chicago.
What's hard to ignore is the fact that they're hitting the high notes a lot smoother, well, because autotune. They're obviously all having fun and with a really awesome name to call their group, let's all hope this isn't the last time Federer and his gang are serving up this type of performance.
An added bonus? Novak Djokovic makes a cameo, too.
