SIR Paul McCartney has apologised for “letting my fans down” after scrapping a concert tour of Asia because of a mystery virus.
The ex-Beatle had to cancel one show after falling ill last week but now doctors have ordered him to abandon his entire tour of Japan and South Korea.
A statement on the star’s website yesterday said: “Doctors have ordered Paul complete rest and he has been doing all he can to get better.
“Paul has only ever had to reschedule a handful of shows in his entire career and is so upset about this situation.
“He hates to let people down.”
It said the 71-year-old had wanted to perform despite medical advice but was “convinced not to.”
Macca himself added: “Unfortunately my condition has not improved overnight.
“I’m so disappointed and sorry to be letting my fans down.”
Sir Paul had been due to perform at the Nippon Budokan hall in Tokyo last night – 48 years after The Beatles graced the same stage in 1966.
But organiser Kyodo Tokyo was forced to tells fans the shows were cancelled.
Last night hundreds of famously fanatical Japanese fans were gathering outside the hotel where Sir Paul is recovering.
The mystery illness comes on the heels of a trek through South America in support of his 2013 album, New.
Sir Paul and his band recently completed a tour there, which included concerts in Peru and Uruguay.
Fans worldwide have been left alarmed by news of his illness a month before his 72nd birthday on June 18.
But a source close to The Beatles legend assured the Daily Express: “It is nothing serious.”
Macca’s next scheduled performance is not until mid-June, when he plans to kick off an extensive leg of North American tour dates, starting in Texas.
There is no suggestion at this stage that those shows are in jeopardy.
Japanese fans are among the world’s most avid followers of Western pop music.
Sir Paul’s website statement acknowledged this, saying: “I’d like to thank my Japanese fans for their love, messages of support and understanding.
“I hope to see you all again soon. Love, Paul.”
The star, who has been performing for more than 50 years, is famous for his relentless work ethic.
The health-loving vegetarian gargles with salt water before every gig and regularly meditates after learning the technique from Maharishi Mahesh Yogi in the 1960s.
He also practises yoga.
The family man is happily married to his third wife, the American heiress Nancy Shevell.
