A lot of these songs, I just lost them.

They only exist in these recordings.

For so long I rebelled against the term [folk singer], I was never a folk-singer.

I would get pissed off if they put that label on me.

I didnt think it was a good description of what I was.

And then I listened and…it was beautiful.

It made me forgive my beginnings.

And I had this realization…I was a folk singer!
