Hey, folks,
The Star Spangled Banner does not have a huge range -- about an octave and a half. It's just hard to sing when done in unison by people with varying vocal registers. [I personally have more vocal trouble with "Spanish Eyes."]

There is another thread related to this. See "America, The Beautiful.

BTW, how come nobody mentions "Stars And Stripes Forever?" It's my favorite march ( and I do a mean rendition of the whole piece on the kasoo, if I do say so, myself).

Here are the main lyrics:

"Hoorah for the flag of the free,
May it wave as our standard forever,
The gem of the land and the sea,
The banner of the right.

Let despots remember the day
When our fathers, with mighty endeavor,
Proclaimed, as they marched through the fray,
That by their right and by their might she waves forever!"

Perhaps the lyrics could be updated to be a little less militaristic at the end, but I love the tune!
