You can contact The Lion King PSM Ron Vodicka via email and he will forward your request to the SM. They're very accommodating and happy to have young people shadow them. I myself shadowed The Lion King twice and I'm thinking about doing it a third time.
"Mostly, I loved the size of these people's emotions. Nobody has emotions this size anymore. Outsized emotions. Operatic emotions. Kushemski and Vanda are like Tristan and Isolde, they're Paolo and Francesca. Nobody's in total thrall like this anymore. Nobody's overcome by passion like this, or goes through this kind of rage." Thomas, Venus in Fur
