The Beatles legend has scored fourth place in The Sunday Times' annual Rich List's Musician's list with a staggering £710 million fortune, with only record label bosses Len Balvantnik - who is worth £10 billion - and Clive Calder, and musicals supremo Sir Cameron Mackintosh placing higher.
Irish rockers U2 collectively placed sixth with a fortune of £428 million, considerably less than fifth-placed Lord Andrew Lloyd Webber, who is worth a huge £640 million.
Seventh place goes to 'American Idol' creator Simon Fuller, with 'X Factor' boss Simon placing eighth thanks to assets of £300 million, a figure £50 million higher than his fortune last year.
He shares eighth place with power couple Mohammad and Kamaliya Zahoor, a record label boss and former Miss World.
'Rocket Man' star Sir Elton John rounds out the top 10 with his £260 million fortune.
Notable names filling out the top 20 include Sir Mick Jagger, who took 12th place with £215 million - two places higher and £15 million more than his Rolling Stones bandmate Keith Richards - and former Spice Girls singer-turned-fashion designer, whose joint empire with husband David sees them worth £210 million, putting them in 13th place.
Paul's Beatles bandmate Ringo Star took 18th place with a relatively more modest fortune - £170 million, while Olivia and Dhani Harrison - the widow and son of their late bandmate George Harrison - were placed 16th with assets of £190 million.
The list is based on land, property and other assets such as stocks and shares, racehorses and art.
