I'm going to disagree with GUEST. I have not seen a field-recorded version with that chorus. I would take the field recordings as authoritative guides as to what is "The Bahamian folk song" over Hal Leonard's book.

The version Lomax collected in 1935 goes approximately like this:

Histe Up the John B. Sails, Cleveland Simmons group, Bahamas 1935 – Deep River of Song (Coll. Alan Lomax), Rounder 11661 – 1822-2

Histe up the John B. sails
(See how) the mainsail set
Then send for the captain 'shore
Let me go home (Let me go home)
O let me go home (Let me go home)
O let me go home (Let me go back home)
I feel so break up
I want to go home

Now the captain and the mate get drunk
Then they broke up the people trunk
I goin' to send for the captain 'shore
Let me go home (Let me go home)
O let me go home
O let me go home
I feel so break up
I want to go home

Grandpa, Ma and me
Was standin'on the railroad block
Go send for the captain 'shore
Let me go home
O let me go home
O let me go home, let me go home
I feel so break up
I want to go home

As for the one Lomax published in is 1960 book, that one went like this:

THE JOHN B.'S SAILS

So h'ist up the John B. 's sail,
See how the mains'l's set,
Send for the captain ashore,
Le' we go home


      CHORUS:
      Le' we go home,
      Le' we go home,
      I feel so break up,
Le' we go home.


The cap'n an' the mate got drunk,
They broke up the people's trunk,
Send for the captain ashore,
Le' we go home . . . (CHO.)

The cook took runnin' fits
An' broke up all my grips,
Send for the captain ashore
Le' we go home . . . (CHO.)

So does anyone know where the chorus GUEST mentions comes from? Sounds to me like someone made it up, and definitely not a Bahamian ("Tar the Ratlines down" is very 19th century British). Is it from Tom Lewis's recording? If so, I'd guess Tom wrote it!
