"I think maybe [Iggy and I] opened up some new avenues in what his approach could be to in terms of singing. I think he got into a whole new idea of melody lines and stuff, working with me. But on the other hand, I enjoyed working with him with his lyrics, the way he would work with lyrics. It's quite extraordinary. Still something I could never do. He works in a very different way to me."

David Bowie, 1993
