The voice of motor racing and much loved public figure - and the man responsible for introducing millions of viewers to the previously inaccessible world of Formula 1 - tells the story of his incident-packed life, with a brand new chapter on his globetrotting adventures since retirement.Murray Walker is a national treasure. When the man who made famous the catch phrase 'Unless I'm very much mistaken... I AM very much mistaken!!!' announced that he was retiring as ITV's Grand Prix commentator, the media reacted as if the sport itself was losing one of its biggest stars.His reputation for mistakes was the making of Walker. He was the fan who happened to be given the keys to the commentary box - and never wanted to give them back. His high-octane delivery kept viewers on the edge of their seats, while his passion for talking about the sport he loved was matched by an all-encompassing knowledge gained through hours of painstaking research before every race.In his book he writes about his childhood and the influence that his father, British motorcycle champion Graham Walker, had on his career. Failing to match his father's achievements on the track after active service in World War II, he made a successful career for himself in advertising which catapulted him to the top of his profession.An offer from the BBC to take over the commentary seat for their F1 broadcasts was too good to turn down, and it wasn't long before the infamous 'Murrayisms' enlivened a sport which until then had been shrouded in a cloak of unfathomable technical jargon and mind-numbing statistics.He also talks about the biggest changes in the sport over the last 50 years, in particular the safety issues which came to the fore after the tragic death of Ayrton Senna, which he witnessed first hand. His partnership with James Hunt behind the microphone is the subject of some hilarious anecdotes, while his views on drivers past and present such as Stirling Moss, Jackie Stewart, Damon Hill and Michael Schumacher make for fascinating reading.
