First The Beatles: Rock Band Footage Emerges

Paul McCartney's performance at Coachella this past Friday was more than just a mix of classic and newer tunes from the ex-Beatle--it served as the medium to debut the first-ever in-game footage of Harmonix's The Beatles: Rock Band (PS3, 360, Wii).

"It was a night of firsts and was the unexpected, unannounced world premiere of the images from the coming Beatle Rock Band game which played on vast screens throughout Got To Get You Into My Life," reads McCartney's official site.

The footage starts at the 1:30 mark in the below clip, which was noticed by Kotaku. Expect many more details and glimpses as the game's 9/9/09 debut approaches.
