During the next few years they perfected their act with Rosetta as a foghorn-voiced comedian and Vivian as the pretty-but-dumb blonde type. Within a few years they "matured into first-rate vaudeville troupers who wrote much of their music in dialogue." They subsequently played not only in vaudeville, but also in night clubs and on stage in both New York and London. They made their first important Broadway appearance in 1917 at the Winter Garden Theatre in a show with Ed Wynn and Frank Tinney entitled "Doing Our Bit".
