That is great for Ireland and if people like that system, and see it as a system and not a virtue of some kind, have at it. I am still only talking about song circle arrangements, not concerts...and I think noisy pubs where the singer is way amplified and couldn't hear you and the people next to you couldn't hear you but perhaps read your lips...I say decide for yourselves. Would the Germans do Octoberfest that way? Maybe they do. Would the Cornish and Welsh sing that way? Maybe they do too...but in America, as in the portion of NA that they call USA, not to be confused with Greenland, Central or South America or other countries in NA, which would be Canada and Mexico and various territorial islands...we have lots of people from different heritages...German, Scandinavian, Welsh, Eastern European, African. All contributed something and they had different ways of doing things. Anything is fine as long as people agree on it. Just sit in a circle and sing solos...that is not something I would enjoy because I think I have musical ADD. I still want to hear everyone all together all the time. And often you will never see that particular constellation of singers again...why would anyone want to miss hearing them altogether? But to each her own.
