FAO Mr Bridge - in my part of North East London the prevailing folk music ie the music that people actually sing is praise music and gospel. This is full throated powerful music sung from the heart. It has nothing to do with your outdated cliched and inaccurate views of school music teaching that took place 40 years ago. It uses open throated singing from the chest and diaphragm to project the sound.
Its saddoes like you with your outdated and inaccurate views of modern teaching. I know because I teach teachers, who by the way are married have kids and are not the frigid stereotype that you in your ivory tower of stupid prejudice .
Modern singing technique has little to do with opera or classical music its out about producing a sound good for your genre and singing safely and accurately.
