Rock ’n roll is really swing with a modern name. It began on the levees and plantations, took in folk songs, and features blues and rhythm. It's the rhythm that gets to the kids – they're starved of music they can dance to, after all those years of crooners.
During 'Saturday Night Fever' at the end of the first act dance number I tried to perform a split-jump, only I can't do them so I ended up on my ass followed by the most unsightly backward roll out of it, followed by the cast falling over in laughter and a good portion of the audience too.
We dance for laughter, we dance for tears, we dance for madness, we dance for fears, we dance for hopes, we dance for screams, we are the dancers, we create the dreams.
All the dancer's gestures are signs of things, and the dance called rational, because it aptly signifies and displays something over and above the pleasure of the senses.
