Green, Green Grass Of Home lyrics

It's good to touch the green, green gra-ass of home
The old home town looks the sa-ame
As I step down from the train
And there to meet me is my mamma and pappa
And down the road I look, and there runs Mary
Hair of gold and lips like cherries
It's good to touch the green, green gra-ass of ho-ome
Yes, they'll all come to meet me
Arms a-reaching, smiling sweetly
It's good to touch the green, green gra-ass of ho-ome,
The old house is still standing
'Though the paint is cracked and dry
And there's that old oak tree
That I-I used to play on
And down the lane I walk with my-y sweet Mary
Hair of gold and lips like cherries
It's good to touch the green, green grass of ho-ome
Yes, they'll all come to meet me
Arms a-reaching, smiling sweetly
It's good to touch the green, green gra-ass of ho-ome
Then I awake, and look around
At the grey walls that surround
And I realize that I was o-only dreaming
For there's a guard and a there's a sad old padre
Arm in arm we'll walk at daybreak
Again, I'll touch the green, green gra-ass of ho-ome
Yes, they'll all come to see me
In the shade of that old oak tree
As they lay me 'neath the green, green gra-ass of ho-ome
