"Walk" comes from The Wiggles, an Australian children's music group formed by Anthony Field, Murray Cook, Jeff Fatt, and Greg Page, who met while studying to become pre-school teachers. The group's background in early childhood education undoubtedly informs their music. This song, appearing on their album Yummy Yummy, is a joyful invitation to movement and exploration for young listeners. It plays like a simple, encouraging tune designed to get children up and moving their bodies.
