Roger Federer, Grigor Dimitrov and Tommy Haas are starting a boy band, or so the world hopes. The trio performed Chicago's "Hard to Say I'm Sorry" and put on quite a show in Melbourne.
The men were accompanied by musician David Foster on the piano, who shared some creative names for the future band like 3Rackets and 1hand Backstroke Boys.
Federer will have to put the virtual microphone down in exchange for a racquet soon enough when he takes on Kei Nishikori in the fourth round on Sunday. Dimitrov was a late Saturday night winner over Richard Gasquet to set up a clash with giant slayer Denis Istomin.
