Mayor Michael Bloomberg helped light the Rockefeller Center Christmas tree on Wednesday night, putting a spotlight on a small-town spruce from Pennsylvania and ringing in the holiday season.

The 74-foot-tall Norway spruce was illuminated by 30,000 lights during a ceremony that featured performances by Neil Diamond, Cee Lo Green and Carol King. Justin Bieber and Tony Bennett provided pre-taped performances.

The tree was cut down in Mifflinville, Pa. It’s decorated with 5 miles of lights. The lights will be on until Jan. 7. After that, the Christmas tree will be turned into lumber for the housing charity Habitat for Humanity.

Workers building Rockefeller Center set up the first Christmas tree there in 1931. The first official tree-lighting ceremony was in 1933.
