All that can presently (September 2022) be gleaned about Annie Hart from sheet music covers and by Internet searching is that she was an American vaudeville performer who has been featured on just one work namely Who Threw the Overalls in Murphy's Chowder? (1898) music by George L. Giefer, and published by W. Pilling, New York, USA
Surfers are welcome to contribute any further information about this performer.

The loss of this valuable resource is very sad and a mystery.
