The Rose and the Briar
(Alan Taylor)

Beware the dream that turns to greed
When the flower rejects the seed
When the lover does not yearn
For the swallow's swift return

Too late the lesson has been learned
The flowers withered the letters burned
The fond embrace is just a breeze
Like the touch of falling leaves

Chorus
Take this broken heart of mine
Throw it out like sour wine
Let it burn upon the fire
For you're the rose and I'm the briar

And now the years are rolling on
And I think of what is gone
For what I gained I do not care
And what I lost I hold most dear


I know you want basic chords. However, the YouTube of Allan Taylor singing the song shows he's in an open tuning. How long have you been playing/how good are you? That's not idle curiousity. It will affect how basic the chords need be.
