Three French Canadian folk songs make a superb set for any concert program. “Roll On, My Ball, Roll On” tells a tale of ducks and hunting and silver guns and an evil prince, all the while you can picture a small child rolling a ball down a lane. Provided in the original French, all three songs enable an exploration in French-speaking Canada. The complete set includes “J'ai Cueilli la Belle Rose,” “Petit Rocher,” and “En Roulant Ma Boule Roulant.”
