Full of eccentric and self-deprecating charm, if there is such a thing as a natural-born performer it’s Annabel Marlow. After impishly demanding (via a recorded conversation with her ‘mum’: it is in fact her friend’s mum, as she later explains) that we applaud her onto the stage as if she’s a Glastonbury headliner, she treats the theatre space like it’s her front room, or a large table in a pub in which she is amiably holding court. 

The show’s opening comic note swiftly segues into musical comedy with a bonkers and deliciously honest number about the opposite of being a ‘relaxed person.’ She sings about the time she two-timed identical graphic designers with matching moustaches, regales us with descriptions of a nonsense mash-up of RuPaul’s Drag Race and The Traitors, and confesses with hilarious candour an incident where she exaggerated to her doctor about how much sex she was having. When Marlow gets it right, it’s like Victoria Wood’s spirit has been channelled through the soul of a Gen Z-er with an awesome pop-ballad voice. 

But the show falters when Marlow opts to share some of her more serious songwriting; while sung beautifully, the songs don’t have the same grip as her comic work. There are also moments when she seems to lose her nerve mid ad-lib, and swallows or mumbles a punchline. It’s not a perfect show, but Marlow is still very young and has plenty of time to harness and refine the huge amount of talent and potential she so clearly possesses. 

Annabel Marlow . . . Is This Okay??, Pleasance Courtyard, until 27 August, 8.30pm.
