The chords are sorta syncopated, but it's easy to get if you listen to the song.

Intro: [G  Em] x4

G     Em      G      Em
I had entered into a marriage
G      Em           G            Em
In the summer of my twenty-first year
G       Em         G       Em
And the bells rang for our wedding
G    Em       G           Em
Only now do I remember it clear
  A        C
Alright, alright, alright

[G  Em  G  Em]

G         Em       G         Em
No more a rake and no more a bachelor
G     Em            G          Em
I was wedded and it whetted my thirst
G         Em         G            Em
Until her womb start spilling out babies
G         Em    G         Em
Only then did I reckon my curse
  A        C             G  Em  G  Em
Alright, alright, alright
  A        C
Alright, alright, alright

[G  Em  G  Em] x2

[The rest of the verses follow the same chords]

First came Eziah with his crinkled little fingers
Then came Charlotte and that wretched girl Dawn
Ugly Myfanwy died on delivery
Mercifully taking her mother along
Alright, alright, alright

What can one do when one is widower
Shamefully saddled with three little pests
All that I wanted was the freedom of a new life
So my burden I began to divest
Alright, alright, alright
Alright, alright, alright

Charlotte I buried after feeding her foxglove
Dawn was easy, she was drowned in the bath
Eziah fought but was easily bested
Burned his body for incurring my wrath
Alright, alright, alright

And that's how I came your humble narrator
To be living so easy and free
Expect you think that I should be haunted
But it never really bothers me
Alright, alright, alright
Alright, alright, alright
