Listening to a German cast recording of Die Dreigroschenoper (3Penny Opera) with Rene Kollo as Macheath and Ute Lemper as Polly Peachum. I don't know that I've ever listened to it all the way through before (another dollar purchase). I really like it. And the diction is so good, I can understand a little of the German. Thankfully, the booklet has a German/English libretto side by side.
