Charley Noble, et al,

I find a fourth verse for Saturday Night At Sea (https://mudcat.org/@displaysong.cfm?SongID=5188)
in Huntington, _Songs the Whalemen Sang_, 1964, p66 gives the Clayton/Ship Samuel Robertson verses as Florida 1843 (two years before the "Robertson" log). He gives an additional verse from _Mammoth Songster_, Boston 1866. This may be the same as Dibden.

Come messmates fill the cheerful bowl
Tonight let no one fail
No matter how the billows roll
Or roars the ocean gale
        There's toil and danger in our lives
        But let us jovial be
        And drink to sweethearts and to wives
        On Saturday night at sea.

Huntington adds, "So if the weather was fair, Saturday night meant a little while on deck to sing and relax, and depending on the skipper, perhaps there was even an issue of grog."

(Somehow, the blue clicky flat refused to work.)
