On Bill Edwards' biography of Merrill at Rag Piano, he lists four songs which have been unable to be located or identified. They are: "The Antique Girl" from 1912 with music by Leo Edwards (this might have been confused with a concurrent Broadway musical of the same title), "Back Talk" from 1938 (no composer listed), "Telegraph a Song," an unpublished song from 1939, and "Loose Ankles" another song from 1939 composed by Arthur Freed.
