According to D K Wilgus there were 7 Irish ballads ("only one having anything but praise for the actions of the captain and the crew") on the sinking of the Titanic (article entitled 'Irish Traditional Songs', published in 'Views of the Irish Peasantry', ed. Casey and Rhodes, Archon Books, Conn. 1977)".
I was told that Wilgus claimed there were in the region of 60-odd songs in the English language on the incident.
