Have you ever thought where you would go if you could climb into time machine.

Paul McCartney had the flashback question put to him in reply to a fan`s question - picked from over 10,000 submitted to his website in a new monthly feature - the ex-Beatle has revealed the depth of the heartache.

A fan of Paul McCartney from Brazil asked:"What would you do if you had a time machine?" to which Sir Paul simply replied:"Go back and spend time with my mum." When Sir Paul was just 14 his mother died of an embolism. Her death became a point of connection with John Lennon, whose mother, Julia, had died when he was 17.

Paul’s mother inspired one of his greatest songs Let It Be.
