Jackie Blue...is confusing

I was standing in the shower thinking....no, not about what makes a man (ha, sorry about that), about this song.

Im completely confused. Is said Jackie like, an idiot (a la Fox on the Run), a gal who thinks she knows whassup but doesnt (like, um, hmm, Girl You Need a Change of Mind) or a manipulateress (a la the girl who dumps billy joel in "the stranger" and um, Bianca Jagger in she's so cold?) Pre shower, I thought it was a song about a crazy gal, a la Angie Baby. Albeit a milder version. NO crazy gal song can outdo Angie Baby on the Ophelia Crazy angle. Now that im dried off, im confused again.

what the hell is in the Ozark Mountain Water?

Lyrics.

and where can i get some?

Note: I read somewhere (just now!) that they are a "countrified Steely Dan". Ive mentioned my feelings on "the Dan" and their weird ass creepy songs and how they typify, to me at least, the old bait and switch: you think its a harmless song, then you think about it after and are like, WHAT? Im thoroughly intrigued.
