They say its Paul McCartney s birthday! At 70-years-old, The Cute Beatle is still performing 3-hour concerts to packed stadiums, hopping around the stage like it was 1964. Though it seems like just yesterday  Sir Paul McCartney was with The Beatles, his evolution since has pronounced him a living legend.  From his Teddy Boy days, to the Mop Tops, to the Sgt. Pepper psychedelia, to the Wings-era Mullet, he's lived a thousand looks and affected millions of lives. Let's take a walk down Macca's long, winding memory lane with 70 amazing, rarely seen photos.
