Happy Beatles Day!

It's 09-09-09, and if you've had access to any sort of popular media for the past month or so, you know what that means: It's Beatles Day!
What's your favorite Beatles era, style-wise? I'm partial to their later years myself, for two reasons: First, their style of dressing became so much more flamboyant. And second, the facial hair. Oh, the facial hair. (I'm a fan of Ringo's sideburns, but they're definitely being upstaged by John's beard in this photo.)

Has anyone played Beatles Rock Band yet? Do tell!
