The sheet music for WHERE THE CROSS-EYED CLARAS GROW is listed in the Integrated Catalogue of the British Library, but the only songwriters credited there are Andrew Allen and Wynn Stanley.

The Library of Congress Copyright Office also lists it under the title DOWN IN THE DELL WHERE THE CROSS-EYED CLARAS GROW, with the same 2 songwriters, and furthermore says it's published by Lawrence Wright Music Co., London, 1920.

Unfortunately, I can't find it at the National Library of Australia, which is too bad, because they often have online images available for British songs of this era.
