Yes, I would be interested in playing it too. It had always been my most passionate and favorite games and anything that is associated with Beatles and music always finds place in my classical music world.
I'm not sure which songs are coming out, but the release date is supposed to be September 9th. The game will go for $59.99, the game with guitar will sell for $99 while premium edition (with all instruments) will go for $250. I better start saving my pennies and dimes.
