Paul McCartney and Ringo Starr helped Microsoft kick off its E3 keynote with a wave of harmonized sound: a trailer and gameplay footage from the upcoming The Beatles: Rock Band. The game drops on September 9—coinciding with the release of all 13 of The Beatles’ remastered albums—and includes previously unreleased in-studio commentary.

The 45 tracks bundled in The Beatles: Rock Band include I Saw Her Standing There, Day Tripper and I Want To Hold Your Hand; players will be able to download other songs on Xbox Live, of course, including the entire Abbey Road album. There’s even a charity angle: all sales of the track All You Need Is Love will be donated to Doctors Without Borders. Catch the trailer, complete with trippy I Am The Walrus visuals below ...
