You don't have to be an expert. It's all part of how songs get into the process.

What I've been finding humorous about all this that discussion about what should or shouldn't happen have no affect except to get people involved excited for a few minutes.

Even the poems get folk processed. Consider "Overseas in India..." which originally was "Behind a trench in Flanders..." (CF Smith's "Homeward") It DOES exist along side of the original work just fine.
