From the recording Mostly Melodeon
This song was usually sung at the end of the voyage and at port while sailors worked the pumps and aired their grievances. It could have been sung as early as the time of An Gorta Mór, The Great Hunger, 1845-1850. 'Her' refers to the ship, rather than a woman. Other names for the ballad include Leave
Her Bullies, Time for Us to Leave Her and Leave Her. Mick got this version from the singing of Liam Clancy.
