I was going through some old church bulletins and found this article from April 29, 1984. (queue Footloose theme)

Parents Please Don’t Let Your Teens Go to the Prom
Dancing is a sin. Wait, don’t quit reading. Let me explain. Simply defined, “Dancing consists int he rhythmical movement of any or all parts of the body in accordance with some scheme of of individual or concerted action which is expressive of emotion or ideas.” – Encyclopedia Britanica. Notice, “…body movements…expressive of emotions….” This is the problem of dancing, whether it be the embracing or standing apart and moving the body. The real appeal of dancing is the sex appeal. if not, why do men not dance with men and girls with girls? Can a person with normal sexual drives embrace another or see the movements of the modern dance without being excited? If one can, can his partner? If both can, how long could they? If both can, what about their influence? What does sexual excitement lead to?
Not only that, but dancing is scriptually wrong! It is clearly in the class of “lasciviousness” which means among other things, “…inciting to lust or wantonness.” – J. H. Thayer. Lasciviousness is condemned as one of the works of the flesh, Galatians 5:19-20. It is condemned in 2 Corinthians 12:21; Ephesians 4:19; 1 Peter 4:3 and Jude 1:4. Galatians says that “…they which do such things shall not inherit the kingdom of God.” Does this not mean something to a Christian parent who loves the soul and morals of his child? Does this not mean something to Christian young people who want so much to please God?
Supervising the dance cannot make it right either. Supervision cannot control the mind of the dancers. All the school teachers, police, and parents in town can’t do it. If it’s wrong in the night club, it’s wrong in the school gym.
Parents, please, please, consider these things and impress the importance on the minds of your children. DON’T LET THEM GO TO THE PROM.
The 20th Annual Junior/Senior Christian Banquet will be Friday Evening, May 4 at the Opryland Hotel. Parents, encourange your young people to attend this banquet.
–The Wingate Winner

The line about “Supervision cannot control the mind of the dancers” is classic. Supervision cannot control the minds of attendees to the Junior/Senior Christian Banquet either. Who knows? Those attending the banquet might have an impure thought about their date.
I’m not going to argue about lasciviousness being a sin. Obviously it is a sin. However putting so much emphasis on one act – dancing at the prom – is overkill. In today’s day and age there are alot worse things which could be done besides dancing…
