Here's an interesting attempt back in 1918 to revive "chantie" singing aboard the Merchant Navy:

How Young Americans Are Taught To Man Our New Merchant Marine, 1918

Emergency Fleet News, published by the United States Shipping Board Emergency Fleet Corporation, Philadelphia. May 20, 1918
[Newsletter written for shipyard employees]

Another interesting detail of this service is the chantie singing. On the principle that music improves team work, the United States Shipping Board has appointed an official chantie instructor, Stanton H. King, of Boston, whose duty is to revive chantie singing among our merchant sailors on both steam and sail vessels. Mr. King is considered the best known chantie singer in this country, and has been singing these old sea work songs at a Boston mission for years. He not only knows the old chanties, but how to get the "punch" out of them, and teach them to others.

He is an old salt himself, got his experience in deepwater Yankee ships nearly 40 years ago, and has also served in the United States Navy. For years the chantie singing at his meetings in Boston has been famous, and now he is teaching our new merchant sailors such old sea songs as "Shenandoah," "Bound for the Rio Grande," "Blow the Man Down," "Paddy Doyle," and "Reuben Ranzo."

Cheerily,
