With respect, Joe, I'll offer a couple of slight amendments to your transcription. I pretty sure I got the lyrics from an Ian & Sylvia Songbook I had way back when. Used to have the words & chords on my computer, too, but that was 3 computers and 1 hard drive crash ago!

Play One More
(Words and Music by Ian Tyson)

Play one more, and then I'm leavin', boys
Pick one more, let those guitars ring
I can't tarry here too long, for I do believe
She been high-strung like a swallow on the wing,
She may be gone.

Oh, this smoky, laughing room just seems to ease my mind
Not to mention the few too many that I've had,
So I'll pack my guitar up, for I do believe,
She been high-strung and lately feeling bad,
She may be gone.

Hmmm, Hmmm, hmmmm.

We ain't been getting' along for a month or more,
Yes, I might be better off if she just goes
But to get home with her gone and find an empty room
Could I stand the pain, I really don't think so.

So play one more, and then I'm leavin', boys
Pick one more, let those guitars ring
I can't tarry here too long, for I do believe
She been high-strung like a swallow on the wing,
She may be gone.
