Following rumours that TV producers were courting Paul McCartney and Ringo Starr for a musical reunion at New York's Ed Sullivan Theatre, it has now been revealed that the stars will perform together at this year's Grammys.

The Beatles, who won Best New Artist at the show in 1965, are the 2014 winners of the Recording Academy Lifetime Achievement Award on the night, while McCartney has also been nominated for Best Music Film for concert movie Live Kisses and Best Rock Song with Cut Me Some Slack, his collaboration with the surviving members of Nirvana.

The pair last played together at Starr's 70th birthday in 2010 at New York City's Radio City Music Hall. "We are good friends," Starr told the Daily Mail in 2011. "We don't live in each other's pockets, but if we're in the same country, we get together ... We're the only two who've experienced all this who are still here."

Alongside the previously announced performances from Metallica and Lang Lang and Daft Punk and Stevie Wonder, Taylor Swift, Keith Urban, Kacey Musgraves, John Legend and Macklemore and Ryan Lewis will also play at the event, which takes place at The Staples Center in Los Angeles on 26 January.

To mark 50 years since the Beatles kicked-off American Beatlemania on The Ed Sullivan Show, Annie Lennox and Dave Stewart will also reunite the Eurythmics for the first time in almost a decade, paying tribute to the Beatles at a concert on 7 February. The duo are expected to cover one of their Fab Four favourites alongside performances by Maroon 5, Alicia Keys and John Legend.
