(SHO) BATS Jam-a-thon 08/30/26

To celebrate its 40th anniversary, BATS Improv is opening its doors to the entire Bay Area with a special gift to the community: the BATS Jam-a-thon, a free, community open house celebration of improvisation, creativity, and connection being held on Sunday, August 30, 2026 from 5–11 PM at San Francisco’s Bayfront Theatre. The Jam-a-thon invites audiences of all ages and experience levels to jump into the fun, whether they are seasoned improvisers, curious first-timers, families, or simply looking for an evening of laughter and creativity.

“Forty years ago, BATS was founded on the idea that improvisation has the power to bring people together through creativity, play, and human connection,” said BATS Managing Director Marilyn Langbehn. “The Jam-a-thon is our way of celebrating that legacy by inviting the community to come play with us and experience the joy of improv.”

Throughout the evening, volunteer-led sessions will take place in multiple spaces throughout the Bayfront Theatre, including the main stage, green room, and annex areas. Programming will consist of rotating blocks lasting approximately 45 to 60 minutes and will feature a wide range of interactive activities, including: improv scenes and games; workshop exercises and skill-building sessions; musical improv jams; genre-specific improvisation blocks; specialty skill jams, including stage combat; and more! From 5–8 PM, the Jam-a-thon will feature family-friendly programming and shift to an “adult Swim” atmosphere from 8–11 PM with activities geared toward adult participants. 

The BATS Jam-a-thon is free and open to the public, reflecting the organization’s commitment to making improvisation accessible and welcoming to all. Guests are encouraged to discover the collaborative spirit that has defined BATS for four decades.

Please Note: Improv can be unpredictable! While most BATS performances are suitable for teens and some adventurous middle-schoolers, we recommend considering what other entertainment your child enjoys. We provide general show descriptions—like rom-com, comedy, or drama—and will flag any content that may include violence, such as in “Improvised Kung Fu.” Ultimately, we trust parents to use their judgment in deciding what’s appropriate for their child.
