I can't get Joe's link to work but there is also this article on Dan Leno at The English Music Hall website.

The monologue was called My Wife's Relations and it was included in a LP (EMI World Records; Retrospect Series SH350 1979) "Playing The Halls" of remastered recordings by the original artists. Dan Leno recorded the monologue in 1901.

It is superb, but so much depends on his phrasing and timing that I don't know whether it will come across on the page. I'll try to write down as much of it as I can decipher.
