Young Lentil wants to learn to sing, but no matter how hard he tries he can't sing on key.* He can't even pucker his lips to whistle!* So Lentil learns to play the harmonica instead and beautifully carries his tune through the winding streets of Alto, Ohio.* Lentil masters his craft just as the beloved Colonel Carter returns to town and the Alto residents decide to plan a special celebration.* But Old Sneep, the grouchiest man in town, doesn't want anyone celebrating Colonel Carter's homecoming.* When Old Sneep stops the welcoming parade in its tracks, Lentil's music turns out to be just what Alto needs.
