Lunatic Fringe will celebrate its 20th anniversary on Saturday, April 22, at the Commonwealth Club, 26 Northview Ave.
The event presents Lunatic Fringe cast members past and present in a performance that, as Lunatic Fringe has always done, draws on music and audience suggestions to create a show that’s “different every time but always funny,” according to a release.

Deb Maclean, founder and director of Lunatic Fringe, said in the release, “We’re so proud that we could make people laugh since 1997, the year when Dolly the Sheep was cloned and the first Harry Potter book came out.” One former cast member is coming from Germany to perform. Current cast members include Maclean, Harvey Chipkin, Dave Groveman, Paul Murphy, and Dan Scheinberg. Former cast members include Irene Cooper-Basch, Tom Dean, Glenn Duphiney, Allison Field, Rob Henke, Brooke Hoover, Susan Korn, Beth Nickmann, Brenda Pepper, Michael Scarpelli, and Frankie Spear. Ben Morss plays piano.

Admission is $25 and includes hors d’oeuvres and two drinks after the show. For reservations and information call 973-429-1527.
