Steve Gardham: I was not aware of Bransby Williams. Thanks for bringing him to my attention. The "Make Em Laugh" website has the text of about 30 of his monologues, as well as some biographical information.

YouTube has two recordings of Bransby Williams performing DEVIL MAY CARE; this one (Columbia 2560) has musical accompaniment and this one does not.

I listened to several other recordings by him, and none of them had musical accompaniment.

Your suggestion reminded me of another performer famous for this genre: Stanley Holloway. All of these recordings by him are available on Spotify. I listened to each one of them enough to make sure it was in the correct style.
