The duo came up with "Mr. Dooley", which was interpolated into the 1902 American staging of the London musical "A Chinese Honeymoon". "Chinese Honeymoon" was successful and "Mr. Dooley" became popular. Later that year the song was interpolated into "The Wizard of Oz", extending its popularity. "Mr. Dooley" reputedly sold over a million copies. Their next big hit was "Bedelia" (1903). Interpolated into "The Jersey Lily" and sung by Blanche Ring, it sold over three million copies. By 1904, "Bedelia" had been recorded by four different artists on the three major phonograph labels.
