Right from the opening sequence, you know that there's something different about this edition of Rock Band. The presentation seems better than most, maybe to satisfy the Beatles' demands, I don't know. Like all the other music games, you use your plastic instruments to follow notes on-screen to live out your unfulfilled rock star fantasies. Unlike other music games though, this one exclusively has Beatles tunes and only their tunes. Also, a new addition here is three-part harmonies. The Beatles often had up to three vocalists on their songs, so this new addition makes it possible for up to six people to have fun (1 bass, 1 guitar, 1 drummer and 3 vocalists).
