Lyrics - The Mule by Deep Purple

No one sees the things you do
Because
I stand in front of you
But you drive me all the time
Put the evil in my mind
Used to sing and say my prayers
Live my life without a care
Now
I have become a fool
Because
I listened to the mule
How can
I change when my mind is a friend
Of a lucifer hid in the ground
Just another slave for the mule
