Harold Burke held his trumpet, and his concentration. The young man from Boy Scout Troop 88 played patriotic notes during a Memorial Day service in Schenectady on May 29, 1989. People inside Veterans’ Park listened — and reflected on the men and women who gave their lives for the nation’s freedom. Trumpet players, majorettes and flag wavers have always participated in Memorial Day parades and services. In 1988, people on Crane Street clapped for marchers that included the young Rotterdam Sweethearts.
