PHILADELPHIA (CBS) — Small but powerful voices filled the Kimmel Center with the sound of Christmas. Stratford, New Jersey’s Samuel S. Yellin School’s elementary choir performed their song “Winter Magic” with the Philly Pops Wednesday night.

They won the B 101.10 Christmas choir competition in the K-8 division.
