On Oct. 25, 1971, a 1,076-member marching band paraded down Main Street U.S.A in celebration of Walt Disney World Resort’s grand opening. With trombone in hand, Dave Phillips was among the marching musicians, stepping to the beat of “76 Trombones.” Nearly 50 years later, Dave returned to Magic Kingdom Park during the holiday season to walk down Main Street U.S.A once more, this time with his 5-year-old grandson, Gideon.
