Go on out to the Smithsonian / Folkways web site. You'll find plenty. The Sam Larner recordings are priceless. At ten bucks a CD that stuff can't be beat. The San Francisco Sea Music Festival stuff is great. And the X-Seaman's Institute music (I'm not neutral here---- I've been in a band with a member of the X-, Frank Woerner, and the late Bernie Klay was a friend and mentor).
Tom Sullivan's "Salt Atlantic Chanteys" recorded on an Atlantic crossing on the Brig Unicorn. The real stuff.
Go to the Mystic Seaport web site and order any of the Festival recordings.
Or any of the "Forebitter" music.
Look for recordings by "The Morgans" or by Don Sineti. Stan said Don was the closest to a "real" chanteyman he'd ever heard.
