"I don't think today's younger audience... would even know what 1920s musicals were like"

This quote by Julie Andrews recommends that the younger audience of today would not recognize with the musicals of the 1920s. This might be due to the reality that the 1920s was a very long time ago and the more youthful generation might not have actually been exposed to the musicals of that age. It could also be since the musicals of the 1920s were quite different from the musicals of today. The musicals of the 1920s were typically more easy going and comedic, while modern-day musicals tend to be more major and significant. Furthermore, the musicals of the 1920s were frequently carried out on phase, while modern-day musicals are frequently seen on the big screen. Therefore, it is understandable why the younger audience of today might not recognize with the musicals of the 1920s.
