"Also, what Cowley is saying is exactly my original point -- that chanty-singing and the things a chantwell might do are performances in a similar cultural vein—potentially allowing for slippage of the term chantwell between the various related genres.

A nonviolent carnival chantrel would be leading external praise & holiday fare. "Here's to a great crop. I'm okay. You're okay."

A Canboulay riot girl would be leading self praise and trash talk. "We're the baddest. Resistance is futile."

A tent era calypso chantrel wasn't leading a chorus at all.

An Old Testament Cantor, the chantyman and Harry Belafonte all seek the same goal…

Enchantment - They want to harness the energies of the audience to get something done – Praise the Lord; haul the bowline; pay the rent.

Slippage indeed.
