Milky Way

In the recent commercial for mily way, (The one where the fellow enters his car, looks depressed then grabs a milky way, and opens it to reveal a rather attractive eastern european woman) there is a song that plays VERY BREIFLY during the end. It's some kind of male ensemble singing something like a fugue... The announcer is speaking over it....

does anyone know what that is, and who is performing it?

mmm by the way I lurve yur name.. :wub:
