I occasionally watch the Classic Arts Showcase channel. They play clips (videos, old films) from various performances, such as a scene from an opera, a song or two from a recital, a selection from a ballet, perhaps an excerpt from a classic film, or a selection from someone's night club act.

One of the clips they show from time to time is Marlene Dietrich singing "Where Have All the Flowers Gone." She introduces it by crediting it to Pete Seeger.

Out of her own mouth.

Don Firth

P. S. She sings it like she needs a vitamin shot, but that's another matter. . . .
