It is the same tune as Rosin the Beau, but only the A part..no refrain
I heard Buryl Ives sing this 40 years ago. He also sang holly stones, but, I stick to my story..HOLY stone makes more sense, becaue the smaller one was called a prayer book. I dont just read about going to sea...I've been there, and, I know that landlubbers like Oscar Brand have really mucked up the lingo.
Anyway, believe me, it is HOLY stone.
