May be wrong, but one version with verses that Amsterdam sang to the troops is in Louis Nizer, 1961 (and paperback), "My Life in Court." Verses were added or left out depending on where the entertainer was performing.

On every isle in Caribbean Sea
Native girl dress peculiarly
She wear grass skirt but that's O. K.
Yankee like to hit the hay.

She wear nothing at all from stomach to face
Just to show heart is in right place
She wear sarong like native should
But sarong is only dish towel that "make good."

I bought a dog in Trinidad
Best damn dog I ever had
He's so smart like real "Whiz Kid"
Saw a sign say "Wet Paint," so he did.
(He so smart that little pup
Walk on front legs if you hold back ones up)

In Trinidad out on Green Hill
Lives native man called Papa Bill
He got 65 kids in the Carabeen
He never heard of Ovaltine.
(He got 65 wives but he still feel blue
'Cause he got 65 mothers-in-law too.)

Amsterdam entertained troops in Trinidad and said he wrote the verses after hearing a soldier sing:

Since the Yankees come to Trinidad,
They have the young girls going mad,
The young girls say they treat them nice.
And they give them a better price.

They buy rum and Coca Cola
Go down Point Koomahna
Both mother and daughter
Workin' for the Yankee dollar.

Morey Amsterdam came out of the trial labeled a liar. More likely he was a dupe of Leo Feist and the money men at the recording company, and went along with their theft of Belasco's song. His story of how he got the song may be true; his crime was claiming the melody.

Baron also claimed authorship, but this claim as well was demolished in court. Reliable witnesses were found who knew Belasco in 1906 when he composed the song.

Another interesting part of Nizer's story of the trial concerned Sigmund Spaeth making as ass of himself with his "expert testimony," during the trial. He was forced to admit that his assumptions were incorrect.
