When you mail a letter, you can send it anywhere.
On foot, by truck, by airplane.
The postman gets it there.
So write a letter to a friend, maybe she’ll write you.
No matter what, you always know.
The mail must go through.
(Chorus)
The mail must go through.
The mail must go through.
No matter if it rains or snows.
The mail must go through.
I said
The mail must go through.
The mail must go through.
No matter it rains or snows
The mail must go through.
Some folks live in a city, some live in a little town.
Even if you live out on a farm.
There’s a post man making his roads.
So mail someone a letter, even just a card will do.
You know it’s nice when the postman, has a letter in his sack for you.
