The Metallica version has different lyrics than have been posted. I have never heard the Thin Lizzy version, but I assume that the Metallica version has the same as the Thin Lizzy version.

Here is my interpretation of the Metallica version of "Whiskey in the Jar":

As I was going over the Cork and Kerry mountains,
I saw Captain Farrell and his money he was counting.
I first produced my pistol, and then produced my rapier.
I said stand and deliver, oh the devil, he may take ya,

(Yeah)

I took all of his money, and it was a pretty penny.
I took all of his money, yeah, and I brought it home to Molly.
She swore that she loved me, no never would she leave me,
But the devil take that women, yeah, but you know she tricked me easy

CHORUS: Musha ring dumma do damma da
Whack for my daddy 'ol
Whack for my daddy 'ol
There's whiskey in the jar-O

Being drunk and weary, I went to my last chamber,
Take the money with me, but I never knew the danger.
For about 6:00, maybe 7:00, (yeah) In walked Captain Ferrell,
I jumped up by my pistols, and I shot him with both barrels. (Yeah)

CHORUS: Musha ring dumma do damma da (yeah-yeah)
Whack for my daddy 'ol
Whack for my daddy 'ol
There's whiskey in the jar-O

{Lots of cool Thin Lizzy sounding riffs}

Now some men like the fishin', and some men like the fowlin',
Some men like to hear, to hear the cannonball a' roarin'.
Me, I like sleepin', 'specially in the morning's chamber,
But here I am in prison, here I am with the ball and chain. (Yeah)

CHORUS: Musha ring dumma do damma da (yeah, yeah)
Whack for my daddy 'ol
Whack for my daddy 'ol
There's whiskey in the jar-O (yeah)

ENDING: Whiskey in the jar-O
Musha ring dumma do damma da
Musha ring dumma do damma da
Musha ring dumma do damma da
Musha ring dumma do damma da
