Some of the lyrics to the above were recited when the first cask of salt beef was broached at sea.
One man would say or sing the lines, and the rest would come in on the chorus of "Salt horse, salt horse what brought yer here".
The above seems to have been put together for folkies use, rather than for "sailors use".
Also known as Sailors Grace. For some other versions, see Stan Hugills Shanties From The Seven Seas
