The National Library of Australia has the sheet music of the latter song. The sheet music is not viewable online, but here is the description from their catalogue:

Oddly, I can't find any bibliographic description of [MR] WATERHOUSE'S HOUSE anywhere, either as a recording or as sheet music. Are we sure we have the correct title?
