And from a quick scan of wiki, there seems to be more to it.. As per usual!

It seems that proper balanced signals do indeed require 3 lines, two signal and a ground. However there is a version called balanced line which only needs two, both signal. It seems that it doesn't need ground. I can only assume that grounding is taken care of elsewhere?
