next to of course god america i

I really, really have no idea what to think of this poem. I believe I had it all figured out-- then I read the last line. The quotations makes me believe the speaker is actually speaking or reading something. The last line and the hurried tone leads me to believe the speaker was reading something very rapidly outloud. However, I do not understand the purpose of this hurried tone. I also do not understand the purpose of all the allusions to American songs in the poem. It is mainly made up of classical American freedom songs. The "next to of course god" line leads me to believe the speaker is speaking to an audience who believes in God.
