I know this post is kinda old but those chords can't possibly be right. The song is in A, not in G. And some chords are missing. This is more like it:
A F#m
It was 1962
A E7
I was two years out of school
A F#m
When I got on board
D E7
A boat that was bound for Liverpool
A F#m
The day I went away
A E7
I remember it so well
A F#m
Said goodbye to the North Wall
E7 A
And bid a fond farewell
I put the chords above the text a little bit randomly, just listen to the song to know when to play them. I play this on the mandolin (with the intro and all), but it should be the same on the guitar.
The chords used on the net are from Mother Mo Chroi. Maybe it's played in G? I don't know but it's possible. You can easily convert the song to be played in G anyway if you wish, but to play along the recording it must be played in A.
Edit: and the forum even fucked up the way I wrote the chords. But these are right, just listen to the song and you'll know when to play which.
