The New Bremen High School chorus, under the direction of Patty Ruckman, sings and dances for visitors at Downtown Disney's entertainment and shopping complex on Friday. Earlier in the day the Marching Band, under the direction of Ryan Yahl, performed for people lining Main Street at Walt Disney World. Some 101 students and eight chaperones made the trip aboard two chartered buses - the first such excursion to Florida - as part of Disney's Merry Music Days.
