Not folk but it's a stirring song from way back.
I can't remember it all but another site gives these words:

Wandering the King's Highway - L. Coward

I've always been a wanderer,
summer and winter too.
Traveling the whole world over,
tramping my whole life through.

But when I start my journey,
at the dawn of another day.

I give a health to comrades.
Friends of the great highway.

Chorus:

So, so long to you!
got to be on the road again.

So long to you!
got to hitch up my load again.

Its been great to meet you here.
right good company and right good cheer.

So now then my lads,
would anyone like to come with me?
A wanderer's life is free.
As I go, rain or snow.
Wandering the King's highway.

Parting is filled with sorrow.
But as I roam this land.
I shall meet again tomorrow.
Friends who will clasp my hand.

And when i start my journey
at the dawn of a brand new day.
I and my friendly memories.
Will get up and on our way.

Chorus:

So, so long to you!
got to be on the road again.

So long to you!
got to hitch up my load again.

Its been great to meet you here.
right good company and right good cheer.

So now then my lads,
would anyone like to come with me?
A wanderer's life is free.
As I go, rain or snow.
Wandering the King's highway.

There's another version as well that rings bells:

I've always been a rover
Summer and winter too
Wandering the wide world over
Trekking my whole life through
But as I start my journey
At the dawn of another day
I give a health to comrades
Pals of the great highway:

So long to you
Got to be on the road again
So long to you
Got to hitch up my load again
It's been great to meet you here
Right good company, and right good cheer
Now then my lads
Anyone like to come with me
A wanderer's life is free
I can say, night and day
Nothing ever worries me.

Nights grow cold,
Maybe I'm growing old
Yet I strive
And the pals I meet make it good to be alive
Comrades farewell!
What if we never meet again
The memory will stay:
As I go, rain or snow
Wandering the King's highway.

It's the sort of song my sister and I would belt out back in the 50s.
