’Tis the season to head to City Hall on your lunch break for some holiday tunes echoing throughout the rotunda and sung to you by The City’s children.

Hundreds of them, in fact, will be harmonizing “Hooray for Christmas” and “Feliz Navidad,” among other traditional December melodies.

Most of the students are coming from Longfellow Elementary School, known for its performing arts program, and Junipero Serra Elementary School.

The lunchtime event is on Friday at noon — and don’t be surprised is Mayor Gavin Newsom is there, too.
