 When Sally sees Ben, her former lover, she greets him self-consciously ("Don't Look at Me").Buddy and Phyllis join their spouses and the foursome reminisces about the old days of their courtship and the theatre, their memories vividly coming to life in the apparitions of their young counterparts ("Waiting For The Girls Upstairs").Each of the four is shaken at the realization of how life has changed them.
