In the same year, he made his debut on the Vaudeville circuit with the family band, and an encore performance of "Casey Jones" on the cornet.
Galla-Rini performed on the Vaudeville circuit for twenty years, in that time learning to play 11 woodwind and brass instruments in addition to the accordion, as well as theory in harmony and counterpoint, and operatic and symphonic conducting.
He toured the United States with his family, playing with such Vaudeville stars as Mae West, The Marx Brothers, Jack Benny, Jimmy Durante, and Eddie Cantor.
The Vaudeville ended with the advent of motion pictures with sound, forcing Galla-Rini's family to find other forms of work.
He also founded the International Accordion Teachers' Guild (ATG), in 1941 in Chicago serving as President Emeritus of that society throughout his career.
In addition, Galla-Rini also served as a Vice-President of the Confédération Internationale des Accordéonistes (CIA), a member of the United Nations' International Music Council (IMC).

He joined a rumba band playing at the Trocadero on Sunset Boulevard, leading to invitations to record soundtracks for the Hollywood film industry, playing in many films, including Rhapsody in Blue, High Noon, and The Gunfighter.
