Gibb beat me to it. The "diary" is also here:

"Based on" is the tip-off.


From Basil Lubbock's "The Blackwall Frigates" (1922):

A hundred years is a very long time,
Oh-ho! Yes ! oh-ho !
A hundred years is a very long time,
A hundred years ago.

They hung a man for making steam,
Oh-ho ! Yes ! oh-ho !
They cast his body in the stream,
A hundred years ago. (OLD CHANTY.)

Note the identical, somewhat unusual spelling of "Oho!" in both sources. Lubbock's book, not coincidentally, also includes a skeletal "log" kept by a midshipman on _Agincourt_ in 1848. (I have not compared the accounts any more closely.)

Hugill gives both stanzas, though not consecutively or quite identically.
