"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."

"Like a lot of people of my generation, the first time I heard a Kurt Weill song was The Doors. You go half a lifetime without realising it was written by Brecht and Weill. Recently I went on a journey. I write songs with a guy called Reid Paley. He’s a very less is more, economical songwriter and you know there’s something about him that’s very tin pan alley. He wears a black jacket and a white shirt and has no problem banging out a song. He is not going to use a word like ‘thalossocracy’ in one of his songs. I felt I needed to get into the feel of Threepenny Opera - how has it survived all these years and spawned all these cover versions which are part of the jazz songbook? I really needed to educate myself and listen to that record ten or twenty times to hear the melody and the meter and the drama, what they put together, those dudes back in pre-WW2 Berlin. They were working really hard and we’re still talking about those records today. I was just enjoying it in and my wife was listening along upstairs. She was doing laundry and I was doing pots and pans. And she said: “I could listen to this all day long, whatever it is.” I don’t speak German so I’m missing a lot outside the English part of the libretto but I still love it."
