I was really heartened to see this post from Joe Dale's site today. The post profiles some trainee teachers at Liverpool Hope University being challenged to write their own lyrics to some well known pop songs and coming up with the goods.
I hope all teacher training courses put some element of teaching their students how to lead singing in their lessons. You have to have this skill and it needs to be taught, you don't just turn up in a classroom and put on a video/CD and make it work.
Well done to the teachers and students on this course.
