Who is he? Singer-songwriter, poet, multi-instrumentalist, entrepreneur, record and film producer, artist, animal rights activist. He's estimated to be worth £440m, despite paying out a £24.3m to Heather Mills in a 2008 divorce settlement that was all over the redtops.
How did he make his millions? With 60 gold discs and sales of 100 million singles, McCartney knew a catchy tune when he wrote one. His ditty Yesterday is listed as the most covered song in history - by at least 3,000 artists so far. Ebony and Ivory and much of his later oeuvre take some forgiving, though.
The secret of his success? Although most of the Beatles' songs were jointly credited, there has been much debate about whether McCartney or the late John Lennon was the bigger talent. Either way, there is no doubt who has made the most money. Michael Jackson owned the rights to the Beatles back catalogue, meaning Macca has had to pay to sing his own material on tour. Rumour has it that the rights will revert to McCartney in 2018.
