'Liebe, so heisst meine Welt' is the German version of 'C'est la chanson de mon amour', with which she represented Switzerland at the Eurovision Song Contest in 1972. I bought that single almost a year ago, and this one is the only other version of that song. Even the B-side was translated into German: 'Quand le printemps revient' became 'Der Frühling kommt niemals allein'.
