Blues Traveler - Four - Hook
It's definitely worth noting that the "hook" in this song, aside from the throwaway Peter Pan reference, is the chord progression, which is ripped directly off of Johann Pachelbel's Canon in D. That piece the bane of any classical musician's existance, but dammit, it's catchy.
I think John Popper & Co. chose this progression specifically to illustrate how vacuous yet successful pop songs can be so long as they have a catchy hook.
The next time you go to a wedding and this piece is played (and if the wedding is like most weddings, Canon in D will be played) trying singing the words to "Hook" (above) along with the poor sods stuck playing that progression ad nauseam. It works!
