"where the barkers call the moon down the carnival was ringing loudly now"

I have seen 1 or 2 posters interpret the meaning of "BARKER" in this song.

the song is referring to a Carnival Barker.

A barker is a person who attempts to attract patrons to entertainment events, such as a carnival, by exhorting passing public, describing attractions of show and emphasizing variety, novelty, beauty, or some other feature believed to incite listeners to attend entertainment. A barker may conduct a brief free show, introducing performers and describing acts to be given at the feature performance.

Of course, in the song it may have a duel meaning because dogs are known to bark at the moon.
