Here are the actual lyrics. Sung to the tune of "I'm looking over a four leaf clover".
I had a notion to cross an ocean
That I never crossed before.
I thought for certain that Asia I'd reach
Now something tells me I've hit the wrong beach.
No silks are sold here
There ain't no gold here
Just rain and disease galore
Why did I do it
I really blew it
When I reached the New World shore.
