Yep NLS, "Casper" is the ghost.
Here's a synopsis:
In Casper the Musical, Casper (Paul Tiesler) and his three uncles (LaParee Young, Jamie Torcellini, and Tim Hartman) are ghosts living in Casper's house. They can't "cross over" because Casper is waiting for his parents to return. Before Casper's father left, 50 years previously, he gave Casper the deed to the house, but Casper has forgotten where it is, and the house is set to be demolished by the government to build a highway. Everyone wants to find the deed - there are several reasons for this, but they are not all terribly clear. Magdalena Monteverde (Chita Rivera) is a radio host who wants the deed for a treasure she thinks she will find. She sets up a "reality show" style contest for kids, hoping they will find the deed and she can then take it. The kids in the house at night with the ghosts, the interference of the government representatives, Casper's search for a friend, and the conniving antics of Magdalena are jumbled together throughout the rest of the show.
"The theatre is so endlessly fascinating because it's so accidental. It's so much like life." - Arthur Miller
