4 Non Blondes - "What's Up?"

Nowhere in the lyrics of "What's Up" do the words "what's up" appear.  What's up with that?  This was intentionally done to avoid confusion with Marvin Gaye's signature tune, "What's Going On?".  "What's Up" never found airplay on Adult Contemporary radio stations in 1993, but has since become part of many Hot AC station's gold libraries.
