Rock Band, the karaoke-style game that lets users live out their band dreams, has a new video game coming out and unveiled it at the E3 Video game conference in Los Angeles.

Jon Lennon's widow Yoko Ono Lennon and Olivia Harrison, Paul McCartney and Ringo Starr disclosed 10 of the 45 songs expected in The Beatles: Rock Band when it comes out September 9. All the songs can be bought online via Xbox Live.

The tracks are I Saw Her Standing There, I Want To Hold Your Hand, I Feel Fine, Taxman, Day Tripper, Back in the USSR, I Am the Walrus, Octopus's Garden, Here Comes The Sun and Get Back.

Additionally, they said the entire Abbey Road album will be available for purchase and download, as will other tracks from the band's catalog, after the game's release, and All You Need Is Love will be released exclusively for Xbox 360 users as a downloadable song the day the game hits retail shelves.

Microsoft says all proceeds from the sale of the bonus song will go to Doctors Without Borders, the US branch of the charity Medecins San Frontieres (MSF).

Paul McCartney was enthusiastic. We love the game, it's fantastic, he said.
