It may come as a surprise that Eminem's flamboyant buddy Elton John is an avid sportsman. Having owned a British football club, Sir Elton is also a big tennis buff, and wrote his hit "Philadelphia Freedom" in tribute to the short-lived pro tennis team starring his friend Billie Jean King. Elton is pictured here on court in 1975, rocking a bucket hat and custom sweatshirt combo. Electric boots sold separately.
