Jon Schmidt's Pachelbel meets U2 song, what U2 song is mixed with it?

To me parts sounded like all i want is you but the end definitely sounds like with or without you. you could basically sing along at that point. so i'm not really sure. perhaps it is a compilation and that is why he just said u2 instead of a particular song. but if i had to pick one i would have to say with or without you, based on the end of schmidts song.
