This seems to be as good a thread as any for this tidbit. An impromptu "concert" in the steerage of a packet-ship (Pall Mall Gazette, May 15, 1885).

The "dirtiness" is probably exaggerated, but the attitude of the reporter is of interest:

"THE DIARY OF AN AMATEUR EMIGRANT (From Our Special Correspondent) ...

"A Birmingham man supplied the element of indecency. Right in front of a hundred women he sang one of those abominable chants which have no grace, no wit, no beauty to relieve their dirtiness. I found him to be a good, simple fellow, and I believe he did his best to entertain the company. Strange what kindness and real manliness one finds among men whose vocabulary is all but confined to a selection of oaths and foul phrases! Little by little the disperses, and the hurricane choruses cease."
