Tried-and-true children's songs may seem somewhat out of fashion these days, with the growth of dynamic new material from many outstanding children's artists in recent years. Singer-songwriter Cathy Bollinger, however, knows the value of "tried-and-true" delivered professionally and sweetened with uncloying mom-coziness. Without rendering preschool favorites unfamiliar to little ears, and accompanied by the voices of children, Bollinger deftly gives them her own creative spin, adding new lyrics and musical surprises to "Patty Cake," "The Muffin Man," "The Wheels on the Bus" and other classics. Her own gentle songs, crafted with the same warmth and lilt, are just as accessible-and as easy on adult ears.
