Merry Christmas on a Cold and frosty morning

A chilly morning and the following kept running through my head! 
Merry Christmas everyone.a lovely 10-12mile walk if a little frosty!
 
Three craws sat upon the wa',
Sat upon the wa', sat upon the wa'
Three craws sat upon the wa'
On a cold and frosty morning.

The first craw he's calling for his maw
He's calling for his maw, he's calling for his maw
The first craw he's calling for his maw
On a cold and frosty morning.

The second craw fell and skinned his jaw
Fell and skinned his jaw, fell and skinned his jaw
The second craw fell and skinned his jaw
On a cold and frosty morning.

The third craw had no shirt at a'
Had no shirt at a', had no shirt at a'
The third craw had no shirt at a'
On a cold and frosty morning.

The fourth craw he wisnae there at a'
Wisnae there at a', wisnae there at a'
The fourth craw he wisnae there at a'
On a cold and frosty morning.

And that's a', I ken aboot the craws.
I ken aboot the craws, I ken aboot the craws.
And that's a', I ken aboot the craws.
On a cold and frosty morning.
