There is a very simple way out of this.
First, you explain that you only play radio edit music. No foul or explicit lyrics.
Second, you explain that you play the Top 40 music that the kids want to hear.
Third, you explain that you are inter-active with the kids, keeping them involved with all of the popular group and line dances that kids their age love- Soulja Boy, Chicken Dance, Limbo Dance, Follow Da Leader, Freeze dance, Burger dance, Cha Cha Slide.
Fourth, you explain that there is a far better chance of the kids having more objectionable tunes on their IPODS than you might have in your music library!
---- I do many school dances, in fact just last night I had 350 kids from the 4th through the 8th grade, as well as a dozen high school volunteers helping as chaperon es, for a middle school Halloween Dance.
I used all of these group dances as well as The Funky Style Hokey Pokey---and the dance went off without a hitch. School renewed the contract for 2009.
