Hal Dyson, born in 1884, was a notable composer, songwriter, and music director with a career that spanned several continents and decades. Raised in Launceston, Australia, Dyson initially worked in the town surveyor's office before entering the entertainment industry in 1903 with Alfred Dampier's company. He served as a music director for various companies, including Clarke, Meynell and Gunn's Fatal Wedding company, Albert Goldie's Pantomime Company, and James Brennan's National Orchestra. Dyson contributed new music to a revival of Fred Weierter's 1907 children's pantomime "Robinson Crusoe," which was re-staged in 1910 in Launceston.

In 1913, Dyson expanded his career internationally, moving to South Africa, the United Kingdom, and subsequently the United States, where he worked with New York publisher Kalmar and Puck as a songwriter/arranger. He returned to the theatre industry as a music director and independent songwriter, with significant engagements including working for Lee Shubert.

Dyson's career highlights include the international hit "Let it Rain" and the song "We'll March Along the Road Together," written in 1941 for Australian troops during the war. His compositions were performed by top artists such as Eddie Cantor, Bessie McCoy Davies, and Rube Welch. Dyson continued his work into the 1940s, leaving a lasting impact on the music and theatre industries.
