Blossom Dearie - How do you say auf wiedersehen?

How do you say auf wiedersehen?
To things you'll never see again
The Wilhelmstrasse in the rain
The day we ran to catch the train
That puffed along the river Seine
Remember Paris
And best of all the Pyrenees
Who could forget such memories
That crazy trip how typical of us
To miss the bus the plane too
How do you say auf wiedersehen to these
The wild times the small things
The popular warmth of the day
It ended as all things
But when does the music go away
Say au revoir but not goodbye
I said it 'till I want to cry
Perhaps the French could tell us what to do
I wish I knew, Ah liebchen
How do I say auf wiedersehen to you
