Woman's powerful holiday performance at subway station goes viral

WASHINGTON, DC (WPVI) -- It's a beautiful reminder of what the holiday season is all about.

Singer Tymara Walker gave this gorgeous, impromptu performance of "O Holy Night" at the Union Station subway stop in Washington, DC.

She tells Action News that her 14-year-old daughter Brooklynne recorded the moment.

Apparently, the teen was giggling because the escalator was squeaking while mom was singing.

But all we hear is one amazing voice and a sound and a spirit we can all use right about now.

Social media apparently agrees - the video is going wildly viral.
