McCartney Named U.K.'s Richest Musician
By The Associated Press
LONDON (AP) -- Paul McCartney is Britain's richest musician, according to the Sunday Times' annual list of the country's wealthiest people.
The former Beatle's personal fortune grew by $75 million last year to $1.2 billion, the newspaper said, making him No. 1 among musical moguls, but 29th on the full list.
Composer Andrew Lloyd Webber is ranked second with an estimated $636 million fortune, and producer Cameron Mackintosh third with $533 million.
Madonna, included on the list because she lives in London, ranked fourth with an estimated fortune of $361 million, followed by Robert Stigwood, producer of musicals including "Grease" and "Saturday Night Fever," worth an estimated $316 million.
The newspaper didn't release the name of the wealthiest individual overall. The full list of the 1,000 wealthiest Britons will be published Sunday
