What, tho, does the DT mean by "Irish" at end of Don't Dilly Dally [My Old Man]?? It is lateC19/earlyC20 Cockney music-hall, probably the most famous of all those sung by the great Marie Lloyd.

"My Old Man is a music hall song written by Fred W. Leigh and Charles Collins, made popular by Marie Lloyd.
It is a humorous song, but it also reflects some of the hard aspects of working class life in London at the beginning of the 20th century." Wiki
