Here is the version as sung by Alex Campbell: several of the same verses as in Joe’s original post, but some differences. The verse about “With all men I had my will” variously raises eyebrows or laughs: and I’m not sure what the phrase “be the hangman’s lock” means, or is this a mis-transcription?

"My name is Captain Kidd, as I sailed, as I sailed
?My name is Captain Kidd, as I sailed, as I sailed
?My name is Captain Kidd, and God's laws I did forbid?
And most wickedly I did, as I sailed, as I sailed.

My father taught me well as I sailed, as I sailed
?My father taught me well as I sailed, as I sailed
?My father taught me well to shun the gates of hell?
But against him I rebelled as I sailed, as I sailed.

I murdered Willie More as I sailed, as I sailed
?I murdered Willie More as I sailed, as I sailed
?I murdered Willie More and I left him in his gore
?He was dead for ever more as I sailed, as I sailed.

I steered from sound to sound as I sailed, as I sailed
?I steered from sound to sound as I sailed, as I sailed
?I steered from sound to sound, ran many ships aground
?And many more I burned as I sailed, as I sailed.

With all men I had my will as I sailed, as I sailed?
With all men I had my will as I sailed, as I sailed
?With all men I had my will, and my gunner I did kill
?And his precious blood did spill as I sailed, as I sailed.

The King's ship captured me as I sailed, as I sailed
?The King's ship captured me as I sailed, as I sailed
?The King's ship captured me, no more of piracy
?No more to roam the seas as I sailed, as I sailed.

To the Execution Dock I must go I must go?
To the Execution Dock I must go I must go?
To the Execution Dock while the crowds around me flock
?I'll be the hangman's lock as I go, as I go.

A warning take by me, I must die I must die?
A warning take by me, I must die I must die
?A warning take by me and shun all bad company
?Lest you come to hell with me as I die, as I die.
