Act English is a song created specifically for the stage musical production of Chitty Chitty Bang Bang.
[1] It was written by Robert and Richard Sherman in 2003 as a replacement song for "Think Vulgar".
The song was first premiered at the London Palladium on March 15, 2003.
[2] The concept for "Act English" was conceived by book writer Jeremy Sams and director Adrian Noble who felt that "Think Vulgar" was not moving the story along at a quick enough pace.
Although there were disagreements with regard to its necessity, the creative parties have remained friendly throughout the course of the show's long life.
