I have wanted a singing quartet ever since I saw the one on here singing the headless headman, it was so awesome. My dream is a quartet of corpsed skellies singing johnathon coultons "re:brains" if you have never heard of him check out his website or on you tube. His website is his name . com, he has some great tunes that would be great for halloween. My lack of mechanical abilities is the only thing stopping my quartet dream, well that and the cash involved. Maybe one of you wonderful prop builders will build your own and post the video.........
