'Mostly Sober' by Chris Ross

F
I'm mostly sober these days
I dunno whatcha heard
I only drink on stage
                 B
I only smoke to burn
Away the frivilous things
To write the syllable swings
To fight the urge to go swimmin in the criminal springs
F
Mostly happy these days
Dunno if you read
Between the lines I wrote
               B
And the lines dread to cross over
It's a long way back
When I'm sunk in the saddle and I'm circlin' the cul-de-saq
F
Mostly understand why you couldn't stay
Why the best of you, you went and took away
B
Girl those eyes they be shining like a cigarette
You light 'em up I breathe 'em in until theres nothing left

F

    G
So don't believe the hype or the flowin' hyperbole
B
Mighta done the crime but I never did the perjury
F
Wait for the dust cloud to settle on the rhetoric
B
Even if you rush now you'll never get ahead of it
G
Tip my cup
I tip my cup over
No I ain't got luck I'm just a three leaf clover
   F
I keep my feet on the narrow and the straight
      C
And I ain't too stoned to say
                       F
I'm mostly sober these days

I'm mostly sober these days
I dunno whatcha seen
I only drink to sleep
                 B
I only sleep to dream
Away the cries and the calls I've been listenin'
Put a hole in the walls I'm imprisoned in
F
I'm mostly lonely these days
I dunno where you went
Who you call your friends
                        B
Or how your time gets spent
My last on a ticket back home
One way trip down an east bound road
F
I'm mostly crazy these days
When I think of you
While the earth it shakes
                      B
Girl your aim stays true
Bullseye honey right down the center of
Straight shot through the heart of a sinners love

F
   G
So don't believe the hype or the flowin' hyperbole
B
Mighta done the crime but I never did the perjury
F
Wait for the dust cloud to settle on the rhetoric
B
Even if you rush now you'll never get ahead of it
G
Tip my cup
I tip my cup over
No I ain't got luck I'm just a three leaf clover
  F
I keep my feet on the narrow and the straight
      C
And I ain't too stoned to say
I'm mostly sober these days

To fight the urge to go swimmin in the criminal springs
