The musical was written by Rudetsky and Plotnick with direction by Plotnick. Disaster! was seen in an Off-Broadway run last season. The Los Angeles benefit will take place at the The Los Angeles Theatre Center on Jan. 25, 2015, at 6 PM.

In addition to Rudetsky, the Los Angeles reading will feature Tony Award winner Roger Bart, Tony Award nominee Kerry Butler, Tony Award nominee Kevin Chamberlin, Barrett Foa, two-time Tony Award winner Andrea Martin, original Disaster! cast member Lacretta Nicole, Tony Award nominee Adam Pascal, Drama Desk Award winner Rachel York and Off-Broadway cast member Jennifer Simard repeating her Drama Desk Award-nominated performance as "Sister Mary Downey."

Here's how it's billed: "It's the summer of 1979, and the hottest A-listers are blowing out their feathered hair and putting on their best polyester bell-bottoms and platform shoes for the grand opening of The Barracuda, Manhattan's first floating casino and discothèque. The crowd gathers to gamble and boogie the night away, but their partying is soon interrupted by multiple catastrophes and natural disasters. Can earthquakes, killer bees and tidal waves ruin this epic night of getting-down?"

Disaster! features pop, rock and disco hits of the 70's, including "Hot Stuff," "I Am Woman," "Knock On Wood," "Daybreak," "Signed, Sealed Delivered" and more.

"I love the Actors Fund and I am very proud of our past collaborations on benefit concerts of Dreamgirls, Funny Girl, Chess and Hair. I personally know many people who've been helped by their amazing work and am honored to be able to raise funds for them again," Rudetsky said in a statement. "We were having some trouble getting the rights to Broadway shows to do another concert, so I said 'Why not do a musical where the person who holds the rights is sure to say yes? In other words, myself!' I can't wait to do this concert on the West Coast with my best friend and co-writer, Jack, and this amazing cast we have assembled." Tickets start at $40.
