A list of 19 songs by The Beatles including classics Lucy in the Sky with Diamonds and A Hard Day's Night for a new Rock Band video game were revealed on Tuesday, leaving only one mystery title remaining.

Other new tunes include Ticket to Ride, Helter Skelter, If I Needed Someone and Drive My Car, bringing to 45 the number of titles unveiled so far by MTV Games and Harmonix, which developed the Rock Band series that lets fans play plastic guitars or drums along with music on TV screens.

One more song remains unannounced, the companies said in a statement, but did not disclose when it would be revealed.

The Beatles: Rock Band, which will be released worldwide on September 9, marks the legendary band's first leap into selling their music digitally leading to much speculation on which songs would be used. For years, the Beatles' catalog of songs has not been available anywhere on Web sites such as iTunes.

The game will be compatible with Microsoft's Xbox 360 video game, Sony's Playstation 3 and Nintendo's Wii systems.

MTV has said the game was creatively conceived by former Beatles, Sir Paul McCartney and Ringo Starr, as well as Yoko Ono and Olivia Harrison, the wives of late Beatles John Lennon and George Harrison, respectively.

Since bursting onto the music scene more than 40 years ago, The Beatles have been among the most influential rock acts in history and have sold more than 600 million albums worldwide, including Help!, Revolver, Sgt. Pepper's Lonely Hearts Club Band, Abbey Road and Let it Be.
