The way I hear it is:
Ref: We're in the same boat brother,
We're in the same boat brother,
And if you shake one end, you're gonna rock the other,
We're in the same boat brother,

Lord he looked down, from his holy place,
He said lordy me, what a sea of space,
What a spot to launch the human race,
So he built him a boat for a mixed up crew,
With eyes of black and brown and blue,
So that's why you and I have just one world and just one sky,

Refrain

So the boat rolled on through storm and grief,
Hit many a rock and many a reef,
What kept them going was a great belief
So they had to learn to navigate,
That human race was special freight,
If they don't want to be in Jonah's shoes,
You better be mates on this here cruise,

Refrain

So the boat upblew somewhere in Spain
Oh the tiller was smashed (lyrics please)
Steamboats out from (lyrics please)
What's bad for the bow ain't good for the stern.
If I have to take time (lyrics please)
