The songs above are really creative uses of the pirate theme for a song. I'd love to hear it performed live.

Another suggestion. I find that you can take the idea, modify it, and have quite a bit of fun with it. With the right audience, you can use the style of a limerick. For example, use the words in the notes above about

"he fell on his cutlass,
And rendered him nutlass ..."

Great creative use of the language!

another one I just made up:

A pirate who bragged his was large.
"It gives the young girls quite a charge."
He took off his pants
And the girls stole a glance
And all they could say was just "Argh."

For music, it's pretty simple to find a chord progression that will fit. When I was in my 20's, we had a limerick song that had a silly chorus line (my source was Doug Clark and the Hot Nuts from their fraternity concert days. They had a marvelously bawdy vinyl album.) Chorus was:

"Hot Nuts! Hot Nuts!
You get 'em from the peanut man.

Hot Nuts! Hot Nuts
You use 'em any way that you can"

Then a limerick then the chorus, and another limerick, etc. You can also interpret non-pirate limericks, like:

There once was a coupe named Kelly
Who went around belly to belly
Because in their haste
They used library paste
Instead of petroleum jelly

ETC
