If you had your choice to play one or two songs from high school at our 20 year reunion, which song(s) would you pick?

We will have a professional DJ playing dance tunes in one room and an IPOD playlist playing in another room. There are three different rooms, each one offereing a different theme. Music will be playing in the two end rooms with no music in the middle room so there will be no music "bleeding" over into the other rooms.
