About this show
After becoming a viral sensation, identical twins Carine and Frances land in couples therapy as the world’s most co-dependent non-couple. The session erupts into a hilarious musical intervention and a reckoning that threatens to collapse their lifelong duet. Best known as @thegilberttwins to their 3M+ followers online, Carine and Frances return to their musical theatre roots with their original score co-written by Shona Maule. Loud, ridiculous, and unexpectedly heartfelt, this new musical comedy explores the chaos of sisterhood, online pressure, and the search for your own voice.

In a vibrant success fusing musical theatre with sketch comedy, the twins develop a simple concept into a lighthearted evening of fun.
— The Scotsman (4 out of 5 stars)
For fans of new shows and boundary-pushing work, this is precisely the kind of production worth paying attention to.
Under the Influence is funny, ridiculous, incredibly catchy and then, somehow, properly moving as well.
