If there were very few or "none" commercial chanty recordings in the 1910, and if the few earlier recordings are islands that didn't really impact much that followed, how did a revival of interest in performing chanties (i.e. for fun) grow by the 1920s? What sort of support was there by way of publications (discussed elsewhere), commercial recordings (theme of this thread), and live performances (in a revival-istic vein--and angle I am humbly suggesting is of some relevance to the main theme of this thread)?

In America there was Stanton H. King. I don't have his book at my disposal:

King, Stanton H. King's Book of Chanties. Boston and New York: Oliver Ditson Co.

One of the main things to note is that it came out of his duties as "official chantyman" for the American Merchant Marine, which evidently started during the last year of WWI.

Here are some newspaper excerpts about King that have been gathered by Pam Beveridge on her Heirlooms Reunited Blog.

Official chantie man for the American Merchant Marine is a brand new war job now being held down by Stanton H. King, of Boston. King is to revive chantie singing among the young sailors of Uncle Sam's new cargo ships. An old salt, who first went to sea from the Barbadoes thirty-eight years ago, and who for years sailed on deep-water Yankee ships, King shows that a good chantie is worth an extra hand. He is the best known singer of sailor songs in the country. "Many a time when things were going wrong, a fellow yo-h-ing a lively song has put strength into all our arms", said King. "You know the sailor has a sweetheart in every port. But the sailor's heart is not easily broken, for when one nymph leaves him, he speedily turns to another. Here's a harrowing pang: 'How I missed her, how I missed her, How I missed my Clementine! But I kissed her little sister and forgot my Clementine." We can bring many a fine old chantie up to date for use on army transports. This would go fine in the war zone: ' Masy a gallant ton of coal our bunkers they are full, Poke away my stokers, poke away!'" ...

Stanton H. King of Boston has the only war job of its kind. He is official chantie man of the American Merchant Marine. His work will be to revive chantie singing among merchant sailors who will join the country's new cargo ships through the United States shipping board recruiting service, national headquarters of which are at Boston. While chantie singing has declined on all seas, owing to the change in recent years from sailing vessels to steamers, there not being much opportunity to "heave and haul" on board a steamer - its revival is considered important for two reasons. Mr. King is an old salt and learned chantie singing in its home, on deepwater vessels. He began going to sea 38 years ago from the Barbados, in the merchant service. For six years he served chiefly on deep-water Yankee ships...

Note the use of the word "revival." Who was it that had the idea to deliberately revive chanty singing? And just what were the the "two reasons" why it was important? What did they actually hope to accomplish? If it was mainly to build morale, I wonder how well it succeeded...and if there is a legacy of King's chanties that we can trace down to today among servicemen.
