Sir Paul McCartney and Ringo Starr are to set to perform together at a New York charity concert next month.
The only two surviving members of the Beatles are both on the bill for a show in aid of the David Lynch Foundation at Radio City Music Hall on April 4th.
And though a spokesman for the charity had told the BBC fans would have to "wait and see" whether the former members of the Fab Four would play together, a UK spokesman has now said they will "definitely" perform at least one song.
Tickets for the show - which also features Sheryl Crow, Moby, Donovan and Pearl Jam's Eddie Vedder, go on sale on Monday.
The David Lynch Foundation, established by the groundbreaking filmmaker, promotes the teaching of transcendental meditation to schoolchildren.
McCartney and Starr last performed together in public at a tribute show for their late band-mate George Harrison in 2002.
