This spontaneous solo performance of 'The Star-Spangled Banner' in the gloriously resonant acoustic of the Lincoln Memorial in Washington is very special.
She may have been reluctant and shy at first, but G. Star Swain, a 34-year-old assistant principal from Tallahassee, Florida, has just delivered one of the finest impromptu performances you could hear.
Swain appears hesitant at first, but eventually gives in and launches into her a cappella reading. We're sure you'd agree that she rose to the challenge and absolutely nailed it. It has since gone viral (with very good reason), clocking up over 14 million views on Facebook and YouTube.
Props also to that amazing acoustic.
