In his home-made boat, Rumbles follows the currents, and wrestles the rapids. Mr. Big makes waves, creating a new form of music: rock and roll. Gloria has some watery words to the wise, and the wayward Mouse gets into trouble. Some old favorite songs include: "Red River Valley", "Oh My Darling Clementine", "Rock and Roll Waltz", "Rollin' Down the River", "Down by the Riverside", "Across the Wide Missouri", "Swanne River", "Up A Lazy River" and more!
