Brian Wilson is generally recognized as a musical genius. Heck, even Paul McCartney said Wilson was a big influence on him and called "God Only Knows" the greatest song ever written. But history shows even the famous Beach Boy was capable of imitation on a grand scale. Surfin' USA was the Beach Boys' first big hit and rocketed them to inernational stardom. But it turns out that groovin' beat was lifted directly from the great Chuck Berry, who wrote "Sweet Little Sixteen" several years earlier.
