would it be possible to be 'wordcrazy' in a purely oral society?

I don't know if this counts, quite, but here goes: did you know that there are poets who speak/perform their works, and I don't believe they write them down - because - they use sign language? There's a poetry to the way the hands move that is entirely different from the poetry we get with the use of beautiful, elegant or expressive words. Think the sign language poet is probably wordcrazy! or maybe signcrazy would be more apt....
