Looking for an old Marais and Miranda song. Not sure I have the title right. Fragments I can remember go.

My Sari Marais is so dear to my heart, although we are far, far apart.

(and then a fragment)

She is weeping and a-waiting where the Ruhr River ran. She was before the war began.

Would appreciate help with this one. Think I heard it on the radio in the 1940's.
