Copied from the web site of a Polish band, Cztery Refy:
(They have lots of other chanteys and sea songs there. Click on their "repertoire" button. They have a midi, too, but it doesn't seem to have the right number of notes to match the syllables.)

LINDY LOWE
(Words & music traditional)

Come smiling, Lindy Lowe,
The purtiest girl I know,

CHORUS: On the finest boat that ever float,
On the Ohio!
The Mississippi, on the Ohio!

Come smiling, Lindy Lowe,
To the bayous deep and slow, CHORUS

Come smiling, Lindy Lowe,
To the Gulf of Mexico, CHORUS

Come smiling, Lindy Lowe,
To the Louisiana shore, CHORUS

Come smiling, Lindy Lowe,
'Cause the bell done ring to go, CHORUS

Come smiling, Lindy Lowe,
Before that whistle blow, CHORUS

Come smiling, Lindy Lowe,
Come git on board, or row! CHORUS

"Here's an interesting Mississippi Riverboatman's song, collected by the famous American sailor/author Frederick Pease Harlow."
