Goodnight Irene lyrics

Goodnight Irene, goodnight Irene, I'll see you in my dreams
Sometimes I live in the country, sometimes I live in town
Sometimes I take a few notions, I want to jump overboard in a river and drown.
Goodnight Irene, goodnight Irene, I'll see you in my dreams
One night I got married, now me and my wife settled down
Now me and my wife are parting, I want to jump overboard in a river and drown.
