I disagree. It's an IDENTITY. I wouldn't change a note, and I still get chills when I hear the first drum roll. Regardless of how it came about - it's our national signature, and I'm proud to sing it. It has NO relation to drinking to me, they just adapted the melody and NOT the words. As for the latter verses - not many (including ME) ever even hear them. The first verse is the only part I ever do.
I take pride in having the extra "umpfh" to belt the song out. There is no reason to expect that everyone can sing at all. It's a tough song, but it has a special place in my heart, and no "theory lesson" or comparrison to other songs will change that.
