song for my engagement party

Okay, so I recently got engaged and we're having a party tomorrow night with some friends and family. We made a setlist of songs for the evening and of course I'm going to add some PJ songs to the list. Were starting the set with slower songs, so I put Elderly Woman in there cuz most people recognize the tune and my fiance digs it. As for the upbeat songs, I'm adding Even Flow for pretty much the same reasons. What other songs would you recommend for the occasion? Nothing too depressing, or too heavy. We're trying to throw in songs that most people will recognize, but i'm a die hard fan and want to add something in there good and something that may turn some heads around. Any suggestions?
