TEXAS BLUEBONNETS
Laurie Lewis

Those Texas bluebonnets how sweetly they grow.
O'er all the wide prairies they're scattered like snow.
They make all the meadows as blue as the skies,
Reminding me of my little darling's blue eyes.

Well, I wanted to ramble so I started to roam,
And I didn't think twice about leaving my home,
But when I got to Texas not far from Burnet,
Those Texas bluebonnets wouldn't let me forget.

I ran out of money, went to work on a farm,
Picking their melons and hoeing their corn,
And all winter long, Lord, I herded their cows,
And I tried to forget my little darling somehow.

But then springtime had blossomed [something missing here?]
And it just made my head feel bluer than blue.
Those Texas bluebonnets they smiled in the sun,
But they just made me think of my only one.

I'm leaving the southland. I'm leaving today.
I don't know where I'm going, but I know that I can't stay.
I guess I'll go north to the ice and the snow
Where those Texas bluebonnets never will grow.

In the cold frozen Iceland I'll live 'til I die,
Where I'll finally forget my little darling's blue eyes.
