Bring your picnic basket and enjoy a patriotic concert at Memorial Park. The concert begins at 6:30 with the Haverhill Sons of Italy Drum and Bugle Corps, a group that has been performing in venues such as North End festivals and parades across the region for 70 years. They will be followed by the Georgia Brass Band, a classic band with a national reputation. Appropriately, music director Joe Johnson is a Needham native and graduated from Needham High School in 1983. The band will be followed by the immensely popular "Trooper Dan", the famous former state trooper with the memorable voice. Sgt. Daniel Clark, along with his equally talented opera star wife Mary Colarusso, will serenade the crowd as the stars come out and twinkle overhead.
