Beatles keep fans guessing over 'reunion'

Beatles bandmates Paul McCartney and Ringo Starr are keeping fans guessing about a rumoured reunion at a New York charity concert in April.

The stars are both booked to perform at Manhattan's iconic Radio City Music Hall on April 4 at a bash to aid The David Lynch Foundation - amid rumours they will take to the stage together and wow fans with a duet.

A Foundation release intensified speculation when it claimed the pair would perform together, but McCartney is remaining coy, confirming only that he will do "a few songs on his own".

Director David Lynch formed the foundation to promote meditation in schools. The filmmaker hopes to raise enough money to teach a million needy kids to meditate.

It's a cause McCartney firmly believes in - he credits meditation with keeping him sane and helping him survive five decades in the spotlight.

The 66-year-old said: "In moments of madness, it has helped me find moments of serenity."

And he's convinced it can help at-risk kids too, adding: "I would like to think that it would help provide them a quiet haven in a not-so-quiet world."
