NEW YORK (CNN) -- A victims' rights organization plans to protest Monday night's preview performance of the "The Capeman," Paul Simon's highly anticipated Broadway musical about a notorious killer in Hell's Kitchen whose nickname is the title of the show.
Nancy Ruhe-Munch, executive director of Parents of Murdered Children and Other Survivors of Homicide Victims, said members of the New York chapter will hand out fliers denouncing the use of murder as subject matter for the Broadway musical.
"The name Capeman alone" tells us that the musical glorifies the murders, said Ruhe-Munch. Neither she nor any of the members involved in the planned protest have seen the show.
A relative of one of the victims said he is "sickened" to hear that a show is being done about a cold-blooded killer, but he has no intention of protesting the production.
"It was so long ago, and the families want nothing to do with it," said Cornelius Fanelli, the uncle of Robert Young, one of the two 16-year-olds stabbed to death by "Capeman" Salvador Agron in 1959.
Fanelli said most of the Young family who would remember the crime have since died.
Singer-songwriter Simon said the musical does not glorify Agron or trivialize the murders. He said it is a story about redemption.
The musical tries to articulate some of the pain of the victims' families, Simon said.
"They (the families) were upset. They were afraid this was going to be some kind of glorification of Sal Agron, which it is not," Simon said.
