There is a book called "The Stanley Holloway Monologues" edited by Michael Marshall in 1979, which I believe contains the monologues you are looking for. I have a copy of the Penguin edition of this book. I believe it's still in print, but available only in the UK. (Amazon.com considers it a "special order.")

There is also "Stanley Holloway, More Monologues and Songs" edited by Michael Marshall in 1980, which is out of print. I haven't seen this one.

Then there is "The Book of Comic and Dramatic Monologues" edited by Michael Marshall in 1981. I have seen this book in my local public library. It contains a few monologues as performed by Holloway in addition to lots of others. I think it's out of print, too.

Tom, the monologue you're referring to is called "Brahn Boots." I wasn't able to find it on the Internet, although a search for "Stanley Holloway monologues" turned up 65 references using google.com. If nobody else beats me to it, hopefully I will have it for you in a couple of days.
