LOS ANGELES--If you were among the thousands of people at Microsoft's E3 press briefing on Monday, it's a pretty sure bet that the appearance on-stage there of Paul McCartney, Ringo Starr, and Yoko Ono was one of the most unexpected things imaginable.
Foster said the story begins a couple of years ago, when MTV President Van Toffler ran into Dhani Harrison, son of the late Beatles guitarist George Harrison, in some random social setting.
But being a "Rock Band" fan, Dhani Harrison took his idea to Harmonix CEO and co-founder Alex Rigopulos and began a conversation about what a Beatles version of "Rock Band" could be. Foster said that the idea seemed like a huge challenge, but, deciding to pursue it, Harrison began evangelizing the idea to Apple Corps, the Beatles' U.K. publisher, and its shareholders, particularly McCartney, Starr, and Ono.
And, amazingly, inexplicably, it worked.
