New Delhi, Sep 20 (TIWN) Twenty-time Grand Slam champion Roger Federer has been mesmerising fans with his breathtaking shots on the tennis courts ever since he turned professional in 1998. Now the Swiss legend has left his fans speechless with a rendition of a Beatles' classic.

Federer, who is the Brand Ambassador of the Swiss telecommunication company Sunrise, sang Beatles’ ‘With A Little Help From My Friends’ as part of a commercial for the brand.  The 39-year-old was seen crooning and shaking a leg with other actors for the ad, which promotes, “The more, the better”, showing him starting alone and as he moves ahead people join him and sing along with him.
