A few years ago, no one could imagine that the future of the music business might hinge on a video game that reunites The Beatles. The highly-anticipated Sept. 9 release of The Beatles: Rock Band is a major part of the massive onslaught of Beatlemania to come. Paul McCartney, Ringo Starr, Yoko Ono, and Olivia Harrison approved the video game, called a “grand, meticulous production meant to keep the flame burning and the profits soaring” by Richard Corliss in Time. But will “Love Me Do” revive the music video game industry, whose profits are down 46 percent this year? Reviews for the game are nothing but stellar so far. And for those less adept at handling a fake guitar, all 13 original Beatles LPs will soon be released in a remastered box set by Apple Corps/Capitol.
