"...There's a vast catalog of great songs that bear the stamp of Warren's writing voice and his point of view and his personality and the depth of his character that don't have to be done the way he did them. He had a limited instrument as a singer. But if you love those songs, they're inseparable from the guy who wrote them no matter who sings them. And yet, I always bore allegiance to hearing the writer sing his songs. That kind of flies in the face of the music business."
