Former Beatle Paul McCartney has already revealed that upcoming music game The Beatles: Rock Band will contain songs from throughout the band's career. It's not just going to be the hits you know and love, though - there's going to be some unreleased songs as well.

Dhani Harrison, son of George Harrison , revealed to Billboard that Beatles: Rock Band will include "stuff that has never been heard, never been released." He offered no specific details; a Harmonix PR person then probably hit him with a blow dart and dragged him off before he could say anything else on the subject.

The Beatles: Rock Band will feature 45 songs in total from the band's career. It's set to be released on September 9th, 2009 for the PS3, Xbox 360, and Wii.
