DENVER (Billboard) - The surviving members of the Beatles unveiled new details about their upcoming Rock Band videogame at the E3 videogame conference in Los Angeles.

Joined by Beatles widows 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.

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. The proceeds of the single will be donated to Doctors Without Boarders.

Venues where the Beatles played will be re-created for the game, including the Cavern Club in Liverpool (where they got their start), The Ed Sullivan Show, Shea Stadium and the Budokan in Japan.

The game also will take fans into the studio experience after the band stopped touring through artistic visual expressions known as Dreamscapes, intended to transport players to the imaginative environments that capture the essence of the Beatles' genre-busting musical and fashion transformations during their later years, according to the release.

From a gameplay perspective, the release will break from existing music-based games that allow for only one singer, and add three-part vocal harmonies. Content also will include previously unreleased recordings of the bandmates talking between takes during studio sessions recorded at Abbey Road.

A demo version of the game is available for attendees of the E3 conference to play.
