During an interview with Gamasutra, The Beatles: Rock Band project lead Josh Randall revealed a great anecdote about a playtesting session. "I'm not that great, but the first time I sat in on a playtest session and saw three people singing in harmony together for "Here Comes the Sun," I swear I saw people tearing up at the end," he said. People crying while playing his game? What is this, Shadow of the Colossus?
He also points to another occasion where he saw people "hold hands -- total strangers holding hands, singing in harmony." Randall thinks the game has a lot of heart, and will evoke a lot of emotion from those who play. While we can't comment on that yet, we will say the game's opening cartoon did give us butterflies in our stomach!
