Trying to find who wrote or recorded an old country song I think entitled "The Streets of Berlin" 1st verse is:- I walked away and left her on the streets of Berlin, where we both made a promise that someday we'd meet again etc.
The chorus is:- AufWierdersehen till we meet again by the old river Rhine etc.
