When My Train Pulls In - gary clark jr.

This is the main riff, which can be heard most of the times he is playing Em.
I know Am and B7 might not be 100% correct, but I'm not sure what chord he is playing 
when I watch it live.
This should provide a decent outline of the song. Chord progression is repeated 
the same throughout.

[Verse 1]

Em
 Everyday nothing seems to change.
Em                                                   Am
 Everywhere I go I keep seeing the same old thing & I..
Am                  Em
I can't take it no more.
B7                         Am
 Oh, I would leave this town but I ain't got no where else to go.

Wake up in the morning, oh, more bad news.
& I.. Sometimes I feel like I was borne to lose & I..
It's driving me out of my mind.
I'll catch the next train & I.. I'll move on down the line.


[Chorus]

Whoah I'll be ready now. I'll be ready when my train pulls in.
Whoah I'll be ready now. I'll be ready when my train pulls in.
I know my time ain't long around here.
& I can't live this life again.


[Verse 2]

Walking down the streets you might run across a smiling face.
But they'll stab you in the back as soon as you turn & walk away
& I.. Oh Lord it's bringing me down.
If things don't change around here, ain't no use in me hanging 'round.


[Chorus]

Whoah I'll be ready now. I'll be ready when my train pulls in.
Whoah I'll be ready now. I'll be ready when my train pulls in.
I know my time ain't long around here.
& I can't live this life again.
