[Chord progression I]
Bb                    Cm
   Mary Anne, do you remember
                 Cm 
the tree by the river
                 Bb
when we were seventeen?

(same chords)
Dark canyon wall, the call and the answer
and the mare in the pasture
pitch black and baring its teeth.

I recall the sun in our faces,
stuck and leaning on braces,
and being strangers to change.

Radio and the bones we found frozen,
and all the thorns and the roses
beneath your window pane.


[Chord progression II]
Cm                      Bb 
   Now I'm asleep in a car, I (mean the world?)
       Cm
to a (potty/parted)-mouth girl,
                            Bb
a pretty pair of blue-eyed birds.

(same chords)
Time isn't kind or unkind, you liked to say.
But I wonder to who
(or?) what it is you're saying today.

Bb

Solo (update coming soon)

[Chord progression II]
Now I'm asleep in a car, I mean the world
to a (potty/parted)-mouth girl,
a pretty pair of blue-eyed birds.

Time isn't kind or unkind, you liked to say.
But I wonder to who
(or?) what it is you're saying today.


[Chord progression I]
Mary Anne, do you remember
the tree by the river
when we were seventeen?

Dark canyon road, I was coy in the half-moon;
happy just to be with you,
and you were happy for me.
