KINGSPORT — Mickey, Minnie, Donald, Goofy and Snow White, you’re about to get some musical visitors from the Tri-Cities. They are from the greater Bloomingdale and Lynn Garden communities to be exact. Sullivan North High School’s marching band is headed to Disney World Friday evening and will march in the Magic Kingdom’s Main Street USA parade Sunday afternoon. The Marching Golden Raiders got in a last practice of its rendition of “Hand Clap” in the North gym Thursday afternoon because of the rain.
