Do It. Celebrate John Lennon's 70th birthday.

If John Lennon were still around, he'd be turning 70 years old this Saturday. What would he think of the world? Would he still be making music? Would he and Paul have ever made up, officially?

It'd be weird to imagine him in this world, but it'd be even harder to imagine this world without him, or his music and influence. And so to celebrate the unforgettable singer-songwriter are a few events going on around town. First up is the Grammy Museum's new exhibit called "John Lennon, Songwriter," and which just opened this week and features artifacts like handwritten lyrics, his infamous wire-rimmed round glasses, his uniform from the cover of Sgt. Pepper's Lonely Hearts Club Band, and rare film footage. There are also plans for a candlelight vigil for fans on Saturday at noon at Lennon's star on the Hollywood Walk of Fame.

Furthermore, this week marked the release of a slew of rare and previously unreleased Lennon recordings, including remastered versions of all his post-Beatles songs, a compilation of his greatest hits paired with a DVD of music videos, and remixed versions of his work with Yoko Ono. And beyond that, look forward to the new biopic, Nowhere Boy, being released later this month that'll follow the beginnings of Lennon's musical career.

Happy birthday, John!
