I am building up my teaching career, but am struggling with the majority of my clients...Parents who want music lessons for their kids "just for fun."

I am looking for a method that will work for kids with basically no home practice. More of a club thing...with music appreciation, theory understanding, and pieces that they can learn basically by rote, and simple playing such as from a fake book.

It seems to me, that the trend is to enter your child in 101 different after-school activities, so they get a taste of things... but never progress. Although I would not do this for my kids... I am not out to change the population, but rather alter my services to meet their needs.
Does anyone have a suggestion?
