News of the workshop follows a recent court decision concerning a lawsuit Bruce Singer filed against Henry Bushkin, longtime lawyer of the late Carson. Singer claimed he and Bushkin were partners and was therefore owed money from Bushkin's book, "Johnny Carson." A Los Angeles judge ruled against Singer.
According to a previous Equity casting notice for a September 2014 workshop, Carson has a book by Jamie Malanowski and Bushkin with music by Doug Katsaros and lyrics by Katsaros and Malanowski.
Characters in the new musical include Johnny Carson, Joan Rivers, Rick Carson, Ed McMahon, Ruth Carson, Joanne Carson, Alexis Carson, Fred Silverman and more.
The late Johnny Carson was host of NBC's "The Tonight Show" from 1962-1992. He died Jan. 23, 2005.
