It's America's national anthem, and a historic mystery of the highest order:
Who wrote this manuscript of America's national anthem, The Star Spangled Banner? Not the poem that became the song; that was Francis Scott Key, of course. Who wrote this music manuscript of it; the musical notation and laid out the score?
History Detectives, PBS's hit show that investigates our past, wants to find out. So history detective Elyse Luray and their document expert, John Reznikoff, head to Washington, DC to uncover the author of what many consider America's most important music autograph.
Don't miss the excitement on Tuesday, January 8.
It airs at 8 p.m. on most PBS stations. Check your local listings to confirm the time.
