OK, more 50's: This 1953 Junior Parker/Sam Phillips tune rockabilly classic was recorded by The King at Sun Studios in 1955 as the B-side to "I Forgot To Remember To Forget". It peaked at #11 on the Country charts. Ranked #77 among Rolling Stone's 500 Greatest Songs Of All Time. Scotty Moore's guitar riff evokes Merle Travis' 1946 "Sixteen Tons".
Yesterday's answer: "Kokomo" by the Beach Boys. I saw them do it live in Vegas in Nov. '88 the night it became #1 - they were pretty happy - the fact that they had the UNLV cheerleaders on stage with them made it even better. http://www.youtube.com/watch?v=9_5_AD9wXuY
