Sir Paul McCartney said he was "extremely moved" by the messages of support he has received after he was struck down by an illness that forced him to cancel a string of gigs.
The 71-year-old former Beatle pulled out of tour dates in Japan and South Korea after contracting a virus.
He has been treated for the illness at a Tokyo hospital and is expected to make a full recovery.
A statement released on behalf of Sir Paul said: "Since contracting a virus last week that led to the postponement of tour dates, Paul received successful medical treatment at a hospital in Tokyo.
"He will make a complete recovery and has been ordered to take a few days rest. Paul has been extremely moved by all the messages and well wishes he has received from fans all over the world."
