"Yes, that's the one. I know both recordings, and the movie too, but I think the one I listened to mostly was the later one. In a lot of ways Kurt Weill and Lotte Lenya, and this piece in particular, represent what I'd ultimately like to do as an artist: bringing opera together with popular music; classical singing with everyday life. I've written a couple of operas, I've worked with Shakespeare's sonnets, I've made pop records, and I have this folk background, and I feel that Kurt Weill with The Threepenny Opera was the pinnacle where all of the elements that he was influenced by joined together to create this other animal. Lotte Lenya was the one who interpreted that. It's a really good touchstone to keep in mind in terms of what I do in the pop world and the theatre world."

"I can’t help but include this book on any list I’d ever make of books I love. It is bewitching, playful, poetic, and really beautiful. Ingrid Caven looks like Marlene Dietrich and sings like Lotte Lenya. She was Fassbinder’s muse on film and Schuhl’s in life, and the book creates a fictive plane of reality in between all four, plus postwar German history, plus the 1970s."
