Before getting to its season of staged productions – Neil Simon’s ode to shacking up, “Barefoot in the Park,” and the sexy jazz musical “The Wild Party,” based on the 1928 narrative poem by Joseph Moncure March – the Harvard Square nonprofit theater company Moonbox Productions is starting with its second annual fundraiser cabaret.

The program, “Decadence, Debauchery and Divas,” runs more than 30 area performers through a variety of Broadway musical favorites and throws in tunes from Moonbox’s first five seasons, said creators and hosts Katie Anne Clark and Peter Mill.

That could include everything from the shiny “Godspell” (say what you will about the musical, but one reviewer of the Moonbox production called it “minor theatrical miracle”) to the gripping “Floyd Collins” (the New England Theater Geek site gushed that it was at times “beautiful and haunting”).

The cabaret stars include Dani Apple, Leigh Barrett, Phillip Berman, Teresa Winner Blume, Lucas Cardona, Dave Carney, Allison Choat, Catherine Lee Christie, Kevin Cirone, Shonna Cirone, Katie Clark, Anne Colpitts, Terrell Foster-James, Micah Greene, Alex Grover, Matthew Kossack, Mark Linehan, David Lucey, Carla Martinez, Peter Mill, Davron Monroe, Aaron Michael Ray, Allison Russell, Rick Sherburne, Tom Shoemaker, Damon Singletary, Daniel Forest Sullivan, Phil Tayler, Andrew Winson, Janelle Yull and Matthew Zahnainger.

It’s “a fabulous cast of performers,” said Sharman Altshuler, producer and artistic director for the company, delivering “a toe-tapping, laugh-a-minute celebration of musical theater and Moonbox’s first five years.” Each Moonbox show benefits a nonprofit partner, including such programs as Summer Search, which gives education skills to low-income youth, and Great Barrington’s High Spirit Community Farm, an agricultural work program for adults with intellectual disabilities.

“Decadence, Debauchery and Divas!” runs from 7:30 to 10:30 p.m. Monday at Oberon, 2 Arrow St., Harvard Square. Tickets are $25, with all proceeds and donations benefiting Moonbox Productions’ mission to make top-quality local theater and help area nonprofits increase the reach and impact of their work.
