…what her face was like, I know no longer
I only know I kissed it on that day.
As for the kiss, I long ago forgot it
But for the cloud that floated in the sky
I know that still and shall forever know it.
It was quite white and moved in very high.
It may be that the plum trees still are blooming
That woman's seventh child may now be there
And yet that cloud had only bloomed for minutes.
When I looked up
It vanished on the air.

[Bertolt Brecht, 'Remembering Marie A', from his play 'Baal' (1918).
This translation of the song was recorded in 1981 by David Bowie
