A bad dance saved a hit song

I'm Just Wild About Harry is a song whose rewriting was imposed by the actress Lottie Gee to make it a fast tempo. The initial audience having reacted poorly, the withdrawal of the number was considered when Bob Lee, a replacement unable to perform the planned steps, had to go on stage. He improvised his own choreography with a deceptive smile, which triggered the hilarity of the room and ensured the success of the work.
