RUDY TEPEL and JOE KING!!! boy this is a blast out of the past!!! Rudy was the trumpeteer ( I think) and indeed it was the chassunuh band par excellence!
I was not going to mix in in this discussion but cherrybim is absolutely right. In the fifties and sixties ( I am not sure about the seventies) the chasunnos often did not have a mechitza and, dare I say, there was even mixed seating at times. The minhag chnaged because of the influx of the chassidim and their insistence upon mechitsas and the yeshiva oilam complied.
To think big, do you know why, in the past, the chasunos often were on erev shabbos??
The answer was pure economics. People did not have much money for food and, by scheduling the chassunoh on Friday with the seudas on Shabbos, they saved money as they were able to combine the chasuno seudos with the Shabbos seudas!
