Roger Federer appears to be enjoying life in his tennis retirement and music has been playing a key role in his life now that he has time on his hands.
Federer has attended Coldplay and Taylor Swift concerts as he has got used to life away from the court, yet his connections with tennis continue to linger.
His long-running deal with clothing brand Uniqlo is ongoing, while his investment in shoe company On has been his most lucrative business success away from tennis.
The 20-time Grand Slam-winning icon has also maintained close ties to Wilson, the company that provided him with rackets throughout his tennis career and it was during a promotional event for the sports brand that he made some interesting revelations.
In an interview with the Tennis Channel and show on YouTube, Federer was asked about what song he would pick if he were asked to perform a karaoke song and he offered up a real classic.
