ST. LOUIS, Mo. (KSDK) - By day, they protect and serve; on Saturday night, they sang.

The St. Louis Metropolitan Police Department choir performed a holiday concert, taking the stage at the Henry Givens Auditorium on the campus of Harris Stowe State University.

The choir is one of only a few of its kind in the country. It's made up of officers and civilian employees, along with a few volunteers from the public.
