All that can presently (November 2024) be gleaned about Viva Daron from sheet music covers and by Internet searching is that she was presumably an American actress/singer who has been featured on 3 works published between 1917 and 1925.
Her portrait on the left is taken from A Bachelor Gay (1917) music by James W. Tate, words by Clifford Harris and Valentine, published by Francis, Day & Hunter, London W.C.2, England.
The front cover of Wondering (1925) music by Harry Ruby, words by Bert Kalmar and published by B. Feldman & Co., New Oxford St., London W.C., England describes her as a member of the Lee Sisters.
Surfers are welcome to contribute any further information about this performer.
