Sir Paul McCartney and Ringo Starr has promoted a new computer game featuring Beatles songs.

The remaining members of The Beatles have appeared on stage to launch a new computer game.
Sir Paul McCartney and Ringo Starr attended the E3 Media & Business Summit to unveil the first public viewing of the new Beatles Rock Band game.
Yoko Ono and Olivia Harrison, widows of late Beatles John Lennon and George Harrison, were also at the bash.
The game sees players replicate the guitar, bass and drums of the Beatles' biggest hits and is the first time the band's hits have been licensed to a third party for use.
McCartney commented: "We love the game, it's fantastic."
"The game is good, the graphics are very good and we were great," Ringo added.
Earlier this week, NME.com revealed that Nirvana, Arctic Monkeys, Blur, Coldplay and The White Stripes will appear on the Guitar Hero 5.
In addition, Iron Maiden, Muse, Jimmy Eat World, Queens Of The Stone Age, Kaiser Chiefs and Smashing Pumpkins are tipped to feature on the game.
