I just learned from an answer to this question that one should not use a construction like "beide zusammen" in normal conversation because it is awkward.
But some years ago, I attempted a German translation of the French song, Les Feuilles Mortes,. with a refrain that begins:
Es ist ein Lied,
Dem wir ähneln.
Ich der dich Liebe,
Du die mich liebt.Wir lebten dann,
Beide zusammen.
Is it ok to use "beide zusammen" in a context such as this?
