One of my favorite Marlene Dietrich songs, Black Market, from the film, Foreign Affair (1948)-- a great film with actual scenes of a still-destroyed Berlin in it. Wait for the moment where Marlene passes the cigarette back to the piano player (hot!) who is none other than Friedrich Hollaender, a Jewish emigree who wrote all the songs in the film.
Hollaender wrote other hits popularized by Marlene, including See What the Boys In the Backroom Will Have (another favorite of mine). His wife was named Blandine, which up until now, I did not realize was an actual name.
