How white?

We're trying to figure out what the whitest song out there is, but there are a few rules. It can't be cowboy or country (no John Denver or "Thank God I'm a Country Boy"), it can't be heavy metal / hair band (no "Cum on Feel the Noize" or Def Leppard songs), and it can't be "ethnic" music, because everyone knows Irish drinking songs are white. We're talking WASP-y white music. The leader, so far, is Christoper Cross' "Sailing". I've never heard the song, so I can't say, but is there a whiter song out there?
