Gregg was at the Art Underground in historic downtown Louisville flying as the Wicked Witch of the West, complete with witchy cackling.
The Art Underground is a nonprofit organization that offers dance, theatre, music, photography, film and visual arts to people of all ages.
Lori Jones started the Art Underground in 2007.
"We have lots of activities [here]," Jones said. "We are bringing professional theatre to downtown Louisville."
Jones hopes the kids involved in play will learn a lot from their experiences at the Art Underground.
"We are exposing the kids to professional actors, professional costumes and professional flying systems," Jones said. "[We want the kids to] get presentation skills that they can apply to anything in life."
Their upcoming production of The Wizard of Oz will be the organization's first professional production.
Both the director and choreographer have performed on Broadway.
Opening night is July 15. For information about the Art Underground or to purchase tickets, visit http://www.theartunderground.org/.
