One of the titles mentioned is 'Jack Crosstree'. IMHO this is the sort of title used for songs by Charles Dibdin Sr and his contemporaries towards the end of the 18thc, all of 'em shore songs, usually sentimental tosh that rarely lasted long before the mast. Jack Rattlin', Tom Tackle, Ned Mizzen, Tom Halliard, Old Uncle Tom Bowling and all, old Uncle Tom Bowling and all! Sorry, got carried away.
