Why do we only sing the first verse of the "Star Spangled Banner"?

[blueerica]

A friend of mine is getting ready to become a citizen, and she asked me a damn good question: "Why don't we since more than the first verse of the 'Star Spangled Banner'?"

Now, I knew there was more than one verse, but never posed the question to myself. She said she looked on the Internet last night, but couldn't find an answer to that. I did a quick search this morning, and sure enough - you find websites that talk about how awesome the poem is, give you all the verses, talk about flags, and even famous people who sang (and some destroyed) the song.

I figure that I'll leave the deep searching to others - I've got some of the smartest friends with the most random bits of information stored in their mental lockers.

Does anyone here have a clue into this mystery?
