Like many of the plays and musicals Edgar produced, The Subject Was Roses swiped a Tony Award for Best Play and even a Pulitzer Prize.

Edgar is also credited with taking the acclaimed musical Godspell to the off-Broadway circuit in 1971 and to the Broadway stage in 1976, alongside his producing partner Joseph Beruh.

The producer also worked on a number of screen adaptations of his award-winning stage work including both The Subject Was Roses and Godspell.

Edgar’s other notable production credits include CBS’ Coronet Blue, Blue Sunshine and Lennon.

In 2007, he was presented with The Acting Company’s John Houseman Award to champion his commitment to the development of classical actors and national theater audiences over his four decades in the industry.

His tragic passing comes just two years after his famed sister Angela died in her sleep at her Los Angeles home in 2022.

Edgar’s twin brother, Bruce Lansbury who was also a producer, died in 2017 at the age of 87 after a battle with Alzheimer’s Disease.

A number of tributes have been pouring in for the late producer including actress Peggy Gordon, who appeared in Godspell, mourning “our surrogate daddy” on Facebook.

She penned in a tearjerking message: “Love never dies. It’s an energy that only transmutes into matter. That’s all of us. So, I believe Edgar’s energy continues.”

The producer is survived by his children, David, James, George, Michael, Brian and Kate as well as his second wife, Louise Peabody who he married in 2008.
