Do you want to know a secret?

Fans of the Fab Four can now try their hand (or voice) as one of the legendary rockers in "The Beatles: Rock Band," an extraordinarily fun music game for the Xbox 360, PlayStation 3 and Wii.

This ambitious interactive band simulator takes you through a magical mystery tour of 45 remastered tracks that span The Beatles' career — from their early performances at the Cavern Club in Liverpool ("Saw Her Standing There," "Twist and Shout") and the Ed Sullivan theater ("A Hard Day's Night," "Can't Buy Me Love") to psychedelic Abbey Road-themed backdrops ("Yellow Submarine," "Here Comes the Sun") and their final show on the rooftop of Apple Corps headquarters in London ("Don't Let Me Down," "Get Back").

While "The Beatles: Rock Band" also includes lesser-known tracks, such as "Hey Bulldog" (from 1969's "Yellow Submarine" soundtrack), the game is curiously missing a few classics, such as "Help," "Nowhere Man" and "Hey Jude."

Additional songs can be downloaded for a price, however, including the "All You Need is Love" charity single for 160 Microsoft Points ($1.99; available now for the Xbox 360 only) or complete albums, such as "Abbey Road" (due out in October), "Sgt. Pepper's Lonely Hearts Club Band" (November) and "Rubber Soul" (December).

If you've ever played a song in "Rock Band" or "Guitar Hero," you'll be familiar with how to advance through this new game. Depending on which instrument you're using — the game ships with a guitar-shaped controller, as a complete "band in a box" or by itself if you already own an instrument peripheral — you must strum, drum or sing along with familiar songs and follow the on-screen prompts to hit the correct note or drum at the right time (for singers, it's karaoke-style lyrics that float across the top of the screen). "The Beatles: Rock Band" doesn't mess with this formula, and includes a clever "no fail" option for beginners (so you can't "lose" a song), a thorough tutorial and four difficulty settings.

And what Beatles game would be complete without harmonies? Depending on the song, two or three singers (all on one microphone or separately) can try to hit harmonies to earn "double fab" or "triple fab" bonus points.

Similar to past "Rock Band" games, you can play solo, with friends on the same television or together over the Internet via Xbox Live, PlayStation Network or Nintendo Wi-Fi Connection.

The game includes optional competitive modes, Tug of War and Score Duel.

While you might be concentrating on your playing as John Lennon, Paul McCartney, George Harrison or Ringo Starr, the backgrounds to these songs are magnificent, so catch a glimpse from time to time.

This includes colorful landscapes related to the song, scenes of the animated group (varying according to how they looked at that particular stage in their career), and of course, massive crowds at Shea Stadium, populated by screaming teenage girls.

Every main "chapter" in the game is preceded by an impressive cut-scene video sequence.

Plus fans will eat up the never-before-heard studio chatter between band members, unlockable photos (with optional descriptions) and vintage video clips.

Aside from a couple of song omissions, there's not much to complain about with "The Beatles: Rock Band" — but you'll need to be a fan of the band to want to play this game eight days a week.
