Tex Williams - Empty Letter Lyrics

The train was leaving I had to go
Just a moment left to say our last goodbye
And you had promised now tears would show
But something I said brought the teardrops to your eyes
I said send me an empty letter if you change your mind
Don't try to find the words to explain
Send me an empty letter and let me know you're mine
But today your empty letter came
Oh today your empty letter came
