"This either makes sense to people or doesn't, depending on their orientation."

Aye, I guess the notion is alien to me and I enjoy the combo of individual turns with a percentage of *spontaneously occuring* group singing. I'm only familiar with group singing in a formal choral setting or seasonal carol singing - both of which are fine of course.

If other people prefer that kind of folk-choral stylee singing thing themselves, that's cool and none of my business! Horses for courses.
