In case Metchosin (15 Feb 2000 3:37 AM) is still, 5 years later, interested in that song he quoted, it sure sounds like excerpts from "We Sail The Ocean Blue" from Pinafore.

We sail the ocean blue
And our saucy ship's a beauty
We're sober men and true
And attentive to our duty
When the balls whistle free o'er the bright blue sea
We stand to our guns all day......

A great song in a show full of gems.

I used to sing lots of songs from Pinafore (among many other sources) while mowing lawns when I was 14 and 15. Sure made the time pass a lot quicker.
