Yoko Ono fine after brief hospitalisation

Yoko Ono, the Japanese-born singer, artist and widow of John Lennon, was feeling fine Saturday after a brief hospitalization for flu symptoms, her son said.

Sean Lennon said that the 83-year-old had returned to her apartment in New York, a day after going to a nearby hospital on doctor's advice.

"She's home and running about as usual," Lennon wrote on Twitter.

"Just the flu in the end. I may go get a flu shot now," Lennon said, referring to the influenza vaccine that is encouraged by US health authorities during the winter.

Lennon -- himself a prominent musician who has worked with his mother and the Japanese pop band Cibo Matto -- dismissed initial reports that Ono had suffered a stroke.

"Only stroke @yokoono had was a Stroke of Genius! :-) She's really fine. Thanks for all the well wishes!" he tweeted after the news first broke.

Ono still lives in the Dakota building on the edge of Central Park where Mark David Chapman in 1980 shot dead Lennon, from whom the apparently delusional gunman had earlier asked for an autograph.

Ono has since strived to keep Lennon's legacy alive, including organizing a giant human peace sign in Central Park to mark what would have been his 75th birthday in October.

The artist first met Lennon in 1966 while he was in The Beatles and the two became artistic companions as well as lovers, famously holding "bed-ins" together to protest the Vietnam War.

Ono last week released a remix album, "Yes, I'm a Witch Too," that features versions of her songs reworked with other artists.

Contributors include prominent alternative rockers Death Cab for Cutie and punk rocker turned dark electronic DJ Moby, as well as Sean Lennon.

She has appeared to be in good health, last year playing two concerts with her Plastic Ono Band at New York's Museum of Modern Art and headlining the Chinese-oriented Modern Sky Festival in Central Park.
