Here is my delima with music for kids. I have two children, one especially, that loves music! He has a drum set, a recorder, a harmonica, and sings constantly around the house. I am a working mother with two kids (5 & 3) and I can never find a program that is strictly music - meaning it is not just a dance & playing around type of class - and that fits my schedule.
I would say that the economy has most people cutting back - including me. But, if I could find a class that focuses on music, and I don't mean that he needs to learn notes and fingering at this point, but to understand the beat and the different sounds things make and have fun doing it, I would afford it in some way.
Good luck! And if you do start doing something on the weekends or 6:00 or so, please let me know. I would be very interested.
