Appropiate graduation songs that are popular!?

We are graduationing soon, and we always sing a cl song. Our principal and music teacher decided to pick a song and it was World's Greatest. We don't like it and perfer a different one. We want songs that we all know. Something by Bon Jovi, or whoever. But the problem is, it needs to be appropiate. It can't have a "double meaning". Ex. Don't Stop Believing. (a song about a prostitute.) Thankss :)
