She went on to appear in a number of other hit shows in rapid succession, including Ziegfeld's "Simple Simon" and "Whoopee!". Etting was not originally signed to perform in "Simple Simon"; she became part of the cast at the last minute when vocalist Lee Morse was too intoxicated to perform. Ziegfeld asked Etting to replace Morse; she hurried to Boston, where the show was being tried out prior to Broadway. When Etting arrived, songwriters Rodgers and Hart discovered that the song "Ten Cents a Dance" was not written for Etting's voice range. The three spent the night rewriting the song so Etting could perform it.
