Bob Dylan

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

People are crazy and times are strange
I'm locked in tight, I'm out of range
I used to care, but things have changed.

                                                                  ♦ Things Have Changed

Now you would not think to look at him
But he was famous long ago
For playing the electric violin
On Desolation Row.

                                                                  ♦ Desolation Row
