Prolly not 100% but it's close enough for jazz :-)

Am
It was a half past nothing on a nowhere night
I had no one to love, I had no one to fight
     G                F             Am
So I took a walk down Bad News Avenue

I had a heart full of blood and a head full of booze
I had nothing to gain, I had nothing to lose
So I stepped inside a tavern and began to play

                E
Bad news, bad news
               Am
I'm talking to you
                    G
I don't know your name
                 C/G  E7
But I would love to

                    Am
Next thing I hear "knock knock"
                      G
Who that there at my door?
         F
I hear "knock knock"
   E
I think she's back for more

Well, I woke up in the morning with a bad old head
I had poison in my pocket and a body in my bed
If you can get it with small change it might as well be free

Well the sun came up and the ship went down
I went looking through the gutter for the lost and found
And that's when I saw you smiling back at me

Bad news, bad news
I'm talking to you
I don't know your name
But I would love to

Next thing I hear "knock knock"
Who that there at my door?
I hear "knock knock"
I think she's back for more, say it again
I hear "knock knock"
Who that there at my door?
I hear "knock knock"
I think she's back for more
