Chord/Tab song: Sometimes I Wish

From the Peaks and valleys album. This may be very wrong, as far as I can tell the song
in Open G tuning,
which I'm not overly familiar with in terms of chord shapes etc.
Still, I thought it better to put up my approximation which others might be able to improve,
so please comment with corrections. I think the album version is also done on a 12 string.

Tuning: Open G

D (Low E down 1 step)
G (A down 1 step)
[D]
[G]
[B]D (E down 1 step.

Chords used:

G: 000000
C: X02012
Bm: X40404
Am7 X22012

I haven't put the strumming pattern in these, but you can hear how many times to do each one.

G riff
Sometimes I wish I was born in another time
G riff
A long long time ago
G riff
Things were much harder then
G riff
But I like the clothes they wore
And the way they did their h[C]air
[Bm] At least it took some c[C]are
[Bm] Then they all went off to [C]war
Bm G riff
You can never have it all

Same chord pattern:

Sometimes I wish I was born in another time
Say 1924
People didn't have much money then
In fact, most folks were poor
But what about those cars
And the sound of those guitars
And the voice of Old King Cole
Soothed me to my soul

e|--0----0-----0----0----0--0----0---|
B|--0----0-----0----0----0--0----0---|
G|--12---9---9s11---7--7s9--4--4s7---|
D|--0----0-----0----0----0--0----0---|
A|--0----0-----0----0----0--0----0---|
E|--0----0-----0----0----0--0----0---|

Then the chords: C Bm Am7

Then back to the verse pattern.

Sometimes I wish I was born in another time
In 1754
I'd go drinking with old Robbie Burns
Whose words are made of gold
Oh Christ we need him now
Said a talking Ayrshire cow
But now he's drifted up to heaven
He was only, he was only 37

G riff
Just a young man really
Cut down in his prime

Sometimes I wish I was born in another time
A long long time ago
Things were much harder then
But I like the clothes they wore
And the way they did their hair
At least they showed some flair
Then they all went off to war

You can never[Am7] have it[Bm] all
You can ne[C]ver have it[G] all
You can it s[Am7]ome of the time[Bm]
You can have most things[C] nearly all the [G]time
But you can't have it[C]
[Bm]All of the t[Am7]ime

Repeat intro to finish.

Thats my approximation of it. Like I said, any input is appreciated.
