Lexington High School performance groups (dance, orchestra, band, choir) would perform a series of flash mobs, building up to a finale of community singalong of an original Patriots’ Day song (to the tune of Ode to Joy). Starting from 10 a.m., each 3 – 5 minute flash mobs would occur every 15 minutes, leading up to the finale of 100-200+ full orchestra and choir leading the crowd sing-along at 12 noon. The intended audience includes Lexington residents and visitors of all ages, aiming to foster community spirit and celebrate Patriots Day.
