Louie Louie
While the Kingsmen's version did not top the Billboard chart, it did reach #1 on Cashbox for two weeks, and it was the last #1 before Beatlemania hit the United States with "I Want to Hold Your Hand".  The Kingsmen's version of "Louie Louie" is considered the epitome of garage rock and is often considered one of the greatest rock songs of all time.
