'Isolation' is correct!

In 1984 Julian said, "I'm not trying to carry on a tradition - except maybe in the simplicity of dad's writing. A lot of songs are too complicated these days, and I think if you're going to get a point across, you might as well do it in the simplest way, which is what I learned from him. Like dad's song 'Isolation,' which inspired many of the songs on my album."
