Aerosmith is one thing, but a version of Guitar Hero packed with Beatles songs would be the holy grail for many classic rock fans. Unfortunately, that possibility has seemed as ephemeral as the holy grail itself, as Sony/ATV has been extremely protective of digital distribution of the Fab Four's back catalog (it's not even available on iTunes).
There is some reason to hope though, with L.A. Times reporting that Sony/ATV CEO Marty Bandier has said putting Beatles songs into a Guitar Hero game is "something we have talked about and something I'd like to pursue." Whether that possibility is something Activision would also like to pursue is not yet clear, but if the companies can Come Together, they'd both have a Ticket To Ride right to the bank. Come on Activision, Please Please Us and make this thing happen!
