Here's a somewhat different version:

THE BOLD RAKE

I am a bold rake, and this nation I travelled all round
In search of a fair one, her equal was never yet found;
She was neat in each limb and her skin far whiter than snow,
And if I don't gain her, quite crazy to Bedlam I'll go.

One fine summer's morning to Culgreany chapel I strayed,
Where I fell a courting this innocent harmless maid;
She was so fair a creature, That I could her senses beguile,
I took her in my arms saying, "Darling, don't leave me behind."

That very night up to the town of Roscrea we did stray
And the night after that in the sweet town of Thurles we lay;
When her money was out it was then she began to condole
And I said, "My sweet fair maid, it's better to part and go home."

"O Johnny, if you leave me, that the great God may pity my moan,
How could you deceive me and bring me so far from my home
You promised to marry me and never to alter your mind,
That you'd wed lovely Sally and leave other sweethearts behind."

"Indeed if I said it I'm sure it was far from my heart,
To wed lovely Sally and all other maids for to part,
Let this be a warning to all other maids of your kind,
To beware of a rake or a rambler will leave you behind.

"I will go to my clergy and tell him the bad life I led,
Hoping for pardon for never with you could I wed,
And if he forgives me I'll lead a correct sober life,
I'll go home to Longacre and live with my own lawful wife."
