"I sail over the ocean blue, I catch-a da plenty of feesh; The rain come down like hell, And the wind blow through my wheesk. Oh, Marian, my good compan, O Viva le Garibaldi! Viva, viva, viva l'Italiane!"
Garibaldi was, of course, the soldier who (in a military sense) was most responsible for the unification of Italy. The mention presumably dates the song to the period around 1861 when Cavour (sometimes helped, and sometimes hindered, by Garibaldi) was unifying Italy under the Piedmont dynasty. - RBW
