No song in The Beatles' catalog features as many literary and social references in its lyrics as "I Am the Walrus." In writing it, John Lennon drew inspiration from Lewis Carroll's Alice in Wonderland (the walrus), a playground nursery rhyme that he and his pals sang as children (the line beginning with "yellow matter custard") and the traditional song "Marching to Pretoria."

Paul McCartney was generally known for writing "silly love songs" like "Yesterday" or cheeky whimsy like "When I'm Sixty-Four," but occasionally he could rock every bit as hard as John Lennon. While The Beatles recorded numerous violent rockers, few were more fiery, savage and controversial than McCartney's "Helter Skelter."

It's always nice when members of at least three of the Big Four Bands of British Rock (The Beatles, The Stones, The Who and Led Zeppelin) get together to jam on some old tunes -- and that happened last night, when Paul McCartney (Beatles) invited Roger Daltrey (Who) and Ron Wood (Stones) on stage to perform The Beatles' "Get Back" at London's Albert Hall.

From sweet to rippin’, these ladies know how to make a song their own. Here are 15 takes on Beatles classics, plus a laughable hall of shame mention thrown in for good measure. From rockin’ to sublime, The Beatles are universally appealing, and these covers prove it. Got a favorite I missed? Lemme know!
