I respectfully disagree. It does sound like it has the backbone of the song there, actually.
It starts off with the "We're gonna make it all the way to the light" part but with different lyrics and melody but same chords, then there's a "ooh-ooh" part where Bono sings "Won't you climb the mountain" or something to that effect.
Then the verse sounds principally the same, but again with new lyrics, about soldiers, artists, rockstars and making the world a better place.
To my ears, the bassline seems different somehow, perhaps "playful" is the word I'm after, and still ends with "Oh, a change of heart comes slow...".
Then the chorus has the same lyrics at the start (It's not a hill, It's a mountain/As you start out the climb/Listen for me/I'll be shouting) but after a while he goes into something different. The break section is still there too ("Baby Baby Baby..."), after which the song changes again into some form of extended chorus ("You are not alone....You are not alone") and scat singing.
