Bob Dylan

Now the roving gambler he was very bored
trying to create a next world war.
He found a promoter who nearly fell off the floor, who said:
I've never engaged in this kind of thing before, but –
Yes! I do believe it can be very easily done.
We'll just put some bleachers out in the sun
and have it out on Highway 61!

                                                                  ♦ Highway 61 Revisited

But I learned to accept it
Accept it with pride
For you don't count the dead
When God's on your side.
                                                                  ♦ With God On Our Side

Thunder on the mountain rolling to the ground
Gonna get up in the morning walk the hard road down.
Some sweet day I'll stand beside my king
I wouldn't betray your love or any other thing.

Gonna raise me an army, some tough sons of bitches
I'll recruit my army from the orphanages.
I been to St. Herman's church and I've said my religious vows
I've sucked the milk out of a thousand cows.

I've got the pork chops, she's got the pie
She ain't no angel and neither am I.
Shame on your greed, shame on your wicked schemes
I'll say this, I don't give a damn about your dreams.

                                                                  ♦ Thunder on the Mountain
