All that can presently (November 2023) be gleaned about
Harry James from sheet music covers and by Internet searching is that he was the composer of 2 works published between 1907 and 1914.
Of interest is his
Love Has Come to Live in Our House (1914) published by
Morosco Publishing Company, Los Angeles, California, USA which was performed by
Kitty Gordon and
Fritzi Scheff.
This Harry James is not the trumpeter
Harry James who was born in 1916.
Surfers are welcome to contribute any further information about this composer.
