RtS, you stole my line:
Is dancing sinful?
Only if you're doing it right!

(I attend a Southern Baptist church here in SC, and the pastor jokes about forbidding dancing. Not an active proscription, that I can see. However, I attended a Jazz Liturgy a few weeks ago, at First Presbyterian Church in Davenport, Iowa, during the Bix Biederbeck Jazz Festival. First Pres is my home church, and is the church Bix grew up in. A very talented group of High School and College kids did a song and dance number that included "Give Me That Old Time Religion." All I could think of is that there are probably hundreds of old time Southern Baptists spinning in their graves still, caused by young people mixing that song with (gasp) DANCING! Me... I don't worry about it all.)
