Merry Christmas! Any songs by groups of children are execrable to my ears. It is my opinion, take it for what it’s worth, the only children’s voices that people enjoy are the sounds of their own.
During our timeouts in the OR, I made everyone list their favorite reindeer. Then I asked them to tell their least favorite Christmas song(Santa Baby for me, totally cringeworthy). And yesterday, I asked them to name their favorite childhood Christmas gift. I try and keep things light in there.
As a voice teacher, I sure do understand what you’re sayin’ ! LOL
I can counter your comment by mentioning the Girl Scouts of Nassau County, NY who performed yesterday on Fox & Friends (absolutely outstanding) and anything by Minnesota's Land of Lakes Boys Choir (bone chillingly superb). I would put either of these groups up against any adult professional musicians.
I have to say you are right-once my own cub out grew that lelementary school stage, I no longer found those lisping little voices appealing at all...
