I usually select three songs: one for those who have been married 0-10 years, one for those married 30 years, one for longest married couple. Bride & Groom are tasked with finding out who the longest married couple would be and how long the were married and what their "special" dance song was. I choose the songs for 10 years and 20 years. I ask all married couples to join the newest married couple on the dance floor. At some point during the early part of the evening I usually make an announcement that it might be a good idea for all Husbands to make sure they know how long they have been married because they will need to know that number later in the evening. When it's time to do the Anniversary Dance I explain about all married couples including the B&G are invited to the dance floor for this special dance. I will be calling out numbers during the dance that correspond to the number of married years. When you number has been called, please move to the edge of the dance floor so that when finished the remaining two couples on the dance floor will be the Longest married couple and the newest married couple. Start with music selection number one and let it play about a minute and then start calling out numbers. I usually say "those who have been married less than 5 years please raise your hands." I then ask them to move to the edge of the dance floor. I then start the upward counting...those who have been married 10 years or less. I fade into the next selection and begin from where I left off. Once the floor really thins out...maybe 5 or 6 couples left on the dance floor, I fade into the final song selection. Again, call out the numbers until you have only the Bride & Groom and Longest Married Couple. Stop the music and head over to the longest married couple and with the wireless microphone and ask if they would like to share there thoughts on how they have stayed married so long. If not comments, then I hand the Bride a special bouquet of carnations (Bride has purchased ahead of time). I tell them via the microphone that the bride has a gift for the longest married couple (she presents the longest married bride with the bouquet). That's all there is to it.
