Name that Olympic Theme Song

As I've been watching the first few days of the 2010 Vancouver Winter Olympic Games on television, the television theme song, or at least the clips being used seem to be different. They started out with Leo Arnaud's Bugler's Dream, introduced at the 1968 Winter Olympic Games in Grenoble, France. Then clips of Olympic Fanfare and Theme by John Williams started appearing. That was written for the 1984 Summer Olympic Games in Los Angeles. I'm waiting for another John Williams piece, The Olympic Spirit, written for NBC Sports to use at the 1988 Summer Olympic Games in Seoul, South Korea. After all, there's still lots left of the games to televise.
