All that can presently (October 2023) be gleaned about Belle Hawley from sheet music covers and by Internet searching is that she was presumably an American actress/singer who has been featured on just 2 works published between 1923 and 1925. She was also part of a double-act, namely Watts & Hawley, according the the cover of Tie Me to Your Apron Strings Again (1925) from which her portrait on the left was taken. The music was by Larry Shay, words by Joe Goodwin and published by Milton Weil Music Co., Chicago, Illinois, USA.
