She had a jolly demeanor, and in addition to being a singer she presented herself as a conversationalist in a style that at best anticipates the later Gracie Allen.

Daniel Blum in Great Stars of the American Theatre c. 1952 relates that Cahill was a very proper woman who didn't tolerate naughty behavior or salaciousness.

In 1915 Cahill appeared in her first silent film, Judy Forgot, based on her musical comedy of the same name performed on Broadway in 1911.

[8] In 1917 she appeared in three more silent films; Gladys' Day Dreams, When Betty Bets and Patsy's Partner before giving up on the medium.

Several of Cahill's voice recordings (monologues), made between 1916 and 1924, are on file at the Library of Congress' National Jukebox.
