There is an amazing song on Youtube called Al Zeh haya by Yosef Shick in honor of two bochurim who passed away in Waterbury. My kallah and I feel it works well with Mi Bon siach for our wedding. What do you think?
Popa, you mean we don’t want to take away the one part of the chuppah that doesn’t shtim with aveilus. And I don’t agree that this would, because true aveilus would be have no music (unless you are MO) at all, not even mournful tunes. So I say go for it.
