I love the words, I love the voice and, in those days, I loved the face. Later in her life Joni Mitchell's voice lost the range you can listen to here and became huskier. However Mama Cass's introduction says it all. "This is my friend Joni Mitchell and this is singing". So true

I wish I was 18 again
Look what they done to my song ma.
Both sides now.
The green hills of England.
Follow me.
Best thing that ever happened to me.
The first time ever I saw your face.
