Thank you very much joj! That's a great one.
Strange how Wikipedia lists something different that day.
1845 – Florida is admitted as the 27th U.S. state.

1985 – A magnitude 8.3 earthquake strikes the Valparaíso Region of Chile, killing 177 and leaving nearly a million people homeless.
1931 – The United States adopts The Star-Spangled Banner as its national anthem.
"Unofficial National Anthem: America the Beautiful. For years, people have lobbied to have America the Beautiful's images of the Rocky Mountains and golden wheat waving in the wind replace Francis Scott Key's militaristic "Star Spangled Banner" as the United States' national anthem."
It a heck of a lot easier to sing, too.
