Swimming Elephants Love Diet Coke

This commercial has really stuck with me over the years, as has my enduring love affair with Diet Coke. I'm not sure when it was made, but it still seems chic and funny to me now. (I wonder if it was shot in Hawaii?!) Also, aren't elephants shockingly graceful in water?

P.S) If anyone knows the name of the song playing during this commercial, I'd love to know what it is!
