As the BBC celebrates 90 years of covering Wimbledon, Sue Barker travels the globe to meet some of the legends who have graced the famous grass courts. Tennis royalty including Andy Murray, Roger Federer, Rod Laver, Chris Evert, Billie Jean King, Pete Sampras, Bjorn Borg, Virginia Wade, Martina Navratilova, Boris Becker and John McEnroe share memories and reflect on their own experiences at the iconic tennis tournament. These are their stories as never told before, emotional and self-deprecating, revealing how their lives and careers were changed by the Championships.  For Sue herself, Wimbledon has been a big part of her life for nearly 50 years as a fan, player and broadcaster.
