This is from a live video. My theory's not very good, but the fingerings are all correct.
capo on 6th fret, not sure about the tuning, just experiment with it.

When playing the Asus4 part,try experimenting with hammering on and off the two
strings you are playing with your middle two fingers. it can sound really cool.
You can get the rhythm from listening to the song, its not too hard.

Men walkin' 'long the railroad tracks
Goin' someplace there's no goin' back
Highway patrol choppers coming up over the bridge
Hot soup on a campfire under the bridge
Shelter line stretchin' 'round the corner
Welcome to the new world order
Families sleepin' in their cars in the southwest
No home no job no peace no rest
The highway is alive tonight
But nobody's kiddin' nobody 'bout where it goes
I'm sittin' down here in the campfire light
Searchin' for the Ghost of Tom Joad
The rest of it just goes on like this.
