No, that was the only paragraph that focused on chanties.

Previously they'd battled their way around Cape Horn without any chanties, survived a pamperos, and outsailed the German commerce raider the Seeadler. Then they were stuck in the Doldrums. Once they caught the Northeast Trades and were on their final leg of homeward bound, "chanties" came to mind. It does sound as if they were used more for recreation than for work.
