Lyrics:

Drive you in, drive you in 
I swim 
Down the coast
To the sand 

Raise the sand to the wind 
I'll leave 
See the hills on the land 

Chorus:
I won't come home till after 
I've shaken hands with native lands 
And kiss the old friends back there 
Cause I wanted water 

Drive you in, drive you in 
I swim 
Reach the edge of the shore 
Dive in 

I won't come home till after 
I've shaken hands with native lands 
And kiss the old friends back there 
Cause I wanted water
