Yesterday marked the kick off of the E3 gaming convention, and the first day had a doozy of an announcement: the official trailer for The Beatles: Rock Band (aka Rock Band FTW Over Guitar Hero Edition) was released, in addition to details surrounding the game's track list.

There are ten tracks in the awesome looking trailer above, including:

01 "I Saw Her Standing There"
02 "I Want To Hold Your Hand"
03 "I Feel Fine"
04 "Taxman"
05 "Day Tripper"
06 "Back In The USSR"
07 "I Am The Walrus"
08 "Octopus's Garden"
09 "Here Comes The Sun"
10 "Get Back"

Those ten tracks are just the tip of the iceberg however; the game will feature a total of 45 Beatles songs, which will be announced at a later date. In addition, Harmonix is promising the entirety of Abbey Road shortly after the game comes out on September 9, and the likely future release of other complete albums from the Beatles' discography.

You already know all about the custom guitars and drums that can be purchased when the game comes out, so I won't go there. But what can be learned from the trailer is that the rumored multiple mic support is confirmed; you can actually harmonize on the game. 

The Beatles: Rock Band is due out on X-Box 360 on September 9, and later for other consoles. Go here to pre-order the game. [via Stereogum]
