The Williamsport Area School District’s music department recently presented its 50th annual All-District Choir concert at the Williamsport Area High School auditorium. The program featured the talent of about 300 student singers ranging from grades six through 12, offering a strong sampling of the district’s choral program. Musical selections were played among the blend of students, culminating with Simon and Garfunkel’s “Bridge Over Troubled Water,” performed by the combined student ensemble.
