Lungs Written and Performed by the great Townes Van Zandt
I noticed that the chords in the other version posted on UG seemed to be 
incorrect, though the intro was spot on. Lungs is musically very simple (the 
lyrics are a different story entirely!). You'll only need Em and D.

EmWont (022000@1)you lend your lungs to me
D (xx0232@1)            EmMine (022000@1)are collapsing 
EmPlant (022000@1)my feet and bitterly
D (xx0232@1)                                          EmBreathe (022000@1)up the time that's passing
D (xx0232@1)                           Em (022000@1)              (D)
Breath I'll give and breath I'll take
D (xx0232@1)                                     Em (022000@1)              
And pray the day's not poison
Em (022000@1)                       D (xx0232@1)           EmStand (022000@1)among the ones that live 
Em (022000@1)        D (xx0232@1)   EmIn (022000@1)lonely indecision

The rest of the verses follow the same progression with variations/ repetitions of 
the intro in between them.

Fingers walk the darkness down
Mind is on the midnight
Gather up the gold you've found
You fool it's only moonlight
And if you try to take it home
Your hands'll turn to butter
Better leave this dream alone
Try to find another

Salvation sat and crossed herself
And called the devil partner
Wisdom burned upon a shelf
Who'll kill the raging cancer?
Seal the river at its mouth
Take the water prisoner
Fill the sky with screams and cries
Bathe in fiery answer

Jesus was an only son
Love his only concept
Strangers cry in foreign tongues 
And dirty up the doorstep
And I for one and you for two
Ain't got the time for outside
Just keep your injured looks to you
We'll tell the world we tried
