BATS Improv presents: Spontaneous Broadway 9/5/26 & 9/12/26

Imagine a full-blown Broadway musical made up on the spot! Inspired by your made-up titles, our cast creates original songs and unforgettable characters right before your eyes. You’ll vote for your favorite show-stopping number in Act One, and the winner takes the spotlight in Act Two. Every night is a one-time-only mix of joy, music, and pure improv magic.

Save on groups of 6 or more by emailing grouptickets@improv.org for a discount.

At BATS Improv, one of our core values is respect for our audience. We understand that some people hesitate to sit up front because they’re worried about being "picked on." That’s not our style.

While we may invite audience members to join us on stage, it’s always your choice—and if you do, we’ll treat you with the same respect and playfulness that we bring to the entire show. No embarrassment, no mean-spirited jokes—just a fun, welcoming experience for everyone.

So sit where you like, relax, and enjoy the show!

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.

Refund Policy: Sorry no refunds for our shows at this time.

Cancellation Policy: An event can only be canceled by the venue and/or event organizer. If the venue or event organizer cancels an event, you will be refunded within 4 business days of the event date for your purchase.
