If anyone is looking to expand services for your children with special needs, I wholeheartedly recommend Turtle Dance Music www.turtledancemusic.com with "Mr. Matt."  Matt Mazur has extensive training in music, theater, and special education and seemed to easily assess the audience and include everyone.  He used a wide variety of musical instruments and styles, small and large motor activities, shakey eggs, ping pong ball ABC eye-tracking, puppets, lights, and a slide show that helped kids understand what was coming next.  It was a funny and fun, lively and very entertaining performance that thoroughly engaged the 60 plus people who attended our program -- both typically-developing children and those on the spectrum. Parents were effusive in their compliments after the show. 
He was also a great performer to observe and very easy to work with.
