This little ditty is simple for singers, to be sure. The lyrics are nonsense, repetitious, and silly, so you could even let your youngest singers join in. The real challenge of the piece is the Boomwhacker® performance. There are two parts labeled percussion 1 and percussion 2 on the piano/vocal score. Either part can be played by Boomwhacker® and/or marimbas, xylos, or any pitched percussion you want to throw in. (from Music K-8, Vol. 12, No. 1)
