Roger Federer sings with his new ‘boy band’

The Australian Open seems like it's a lot of fun this year.

Roger Federer, Tommy Haas and Grigor Dimitrov came together to create a boy band. They performed How to Say I'm Sorry, which was co-written by the guy at the piano, David Foster.

Foster does a great job at guiding them through the song. It's pretty wonderful, and the passion is there. They may not know all the words, but they get an A for effort.

On Instagram, Foster posted a photo along with a clever little caption:

new singing sensations "3Rackets!!" (as in noise!!!) also known as "1hand backstroke boys"

Next, the band should sing something with higher notes. Haas has already proven that he can get up there with a decent falsetto.
