What is that song?

[JasonXe]

It was played in Fahrenheit 9/11 when george bush was landing on the navy ship with his line "mission accomplish". It started out as... Believe it or not but ..... it should of been you but it's meeee ...lala something like that.

[GrandpaT]

Was it that old (like from the 70's) song "Believe it or Not" - the theme song from the show The Greatest American Hero?
