I have a song in my head and I can't get it out. Actually it's kind of nice, but I don't know who did it and I know only a few of the lines.

They go like this:

Early in the morning she hitched a ride down to Louisville,
Holding onto a hundred bill.
Dressed herself like a cajun queen in New Orleans, Baby.
Yeah, she looked good like a lady.

(Chorus)

Down on the Bayou, why you never know just what your doing.
Down on the Bayou, why you never know just what your doing.

Please help me with the artist and the rest of the lyrics.

Mick
