A Florida woman's rendition of "The Star-Spangled Banner" at the Lincoln Memorial led to a burst of applause from onlookers — and a hugely popular online video.

The Washington Post reports Star Swain is an assistant principal in Tallahassee, Florida who was visiting Washington, D.C.

In the video Swain says "I'm scared," before launching into the song. After she finishes the final notes, visitors at the memorial cheer.

Benny Bolden, a friend and elder at her church, told the Washington Post it started out as a dare.

Now, the video has millions of views across social media platforms. On Facebook, one posting of the video had over 14 million views. A posting on YouTube had over 175,000 views.
