I dont sign on unless i have to and this is one time where i will sign on.
First of all,i dance with my wife by my mitzva tantz.My firends were there but not all of them.It was a very important part for me.Very holy.The minhag has its roots in many Kabbalistic and Chassidic sources.
I feel like people from Out of Town dont get it and think its only a New York thing because Chassidim dont usually live out of town and its more of a chassidic minhag.
Also, i think you all need to relax.The minhag is to have a chosson to take hold of his Kallah;s hand directly after the chuppah and all of you who are bugging about them touching..they touch then and that is a halacha that they have to acc to many poskim.Secondly, i think its mamash a beautiful thing for a chosson and kallah to dance together in front of people.Brings Hahsme glory in.BH.
