Hello, I am a composer and musician for 50 years. I have worked with kids who have down and autism, in a choir that I directed. We had so much fun with the kids (I call them my kids) Anyway, I can provide you with exactly what you want and need, Any revisions would be free and you would be completely satisfied with the final piece. That;s my guarantee. I also grew up on a farm, so I get the barnyard stylem if that means anything. Good luck, Steve
