How Can I Keep From Singing?

In light of my recent experience with LDS singing, I was pleasantly surprised this past Sunday to experience some singing at the Rise of Meeting. So I posed this question to the OCFM mailing list:

I really enjoyed the singing at the rise of meeting this past week. I know that there's a monthly group that sings before meeting, but I was wondering what the historical discussion has been about including a song at the end of Meeting for Worship.

I've recently been reminded by my friends of other traditions how powerful and comforting song can be, even if it was just singing "As We Leave This Friendly Place" as we head for refreshments, as I remember doing at other Meetings I've attended (no hymn book required).

I thought I was being fairly clear that I was looking for an overview of the past discussion on this issue, but got at least one fairly negative response to my "advocacy."

It feels a little overly dogmatic about not "programming" worship.
