Although described in 1910 as being Scottish, Phil L. Scowcroft indicates that J. A. Robertson was Australian by birth and that he became involved in English musical theatre during the early 1900s. Robertson's name has first been identified to date in connection with John F. Sheridan's Australasian tour (1889-92). Several of his songs were published during the early 1890s including "Because I Love Thee So (1890) and "Stand by your Guns (with Bert Royle, 1892). His other works include: In Sunny Scotland (1901), Winnie Brooks, Widow (1904), Moll the Rogue (1905) and his greatest success, Butterflies (1908, with William J. Locke and T. H. Reade).
