Harmonix creative director Josh Randall has revealed that downloadable content for The Beatles: Rock Band will not be available for other Rock Band games or vice versa.
The Beatles game is a standalone and separate entry in the series, he told 1UP.
We were given a Beatles: Rock Band extravaganza during the Microsoft E3 conference, comprising a fancy a trailer, a live on-stage demonstration by the Harmonix house band and special guest appearances from Yoko Ono, Olivia Harrison, Sir Paul McCartney and Ringo Star.
"The game is great, the graphics are great, we were great," said Ringo, through his big silly lips.
Abbey Road will be the first album DLC for The Beatles: Rock Band, and Microsoft is offering "All You Need Is Love" on Xbox Live and donating the proceeds to charity.
