Could the above sentence be written without 'sobre'? As it would then be similar to the English sentence. If not what difference does sobre make to the meaning of the sentence?
Not really, in Spanish you need the preposition, either "sobre" or "de" before the "theme" you are talking about. So, it'd be incorrect to say "Nosotros estábamos hablando política"
