Hannah Maxwell’s one-person show got a flurry of press early in its run after Phoebe Waller-Bridge made up ‘20%’ of her audience. ‘She said she liked it!’ Maxwell declared in an interview afterwards, now the proud winner of the ultimate Fringe promotional jackpot. For what it’s worth, we heartily agree.

Nan, Me And Barbara Pravi is a semi-autobiographical tale of a particularly conflicted time in Maxwell’s life when she spent her days as a live-in carer for her beloved nan after the death of her grandfather. Terrestrial television drives the show’s narrative, with Mastermind, Countdown and Eurovision becoming interactive set-pieces that further paint our protagonist as a most righteous grandchild. When we see her become increasingly obsessed with a certain French Eurovision contestant, a hunch creeps in that things may not be as they seem. 

Maxwell’s writing is electric, witty and charmingly delivered, efficiently bringing audiences into the intricacies of her character’s daily life while withholding just the right amount of information to be chaotically revealed later. The script is laden with jokes and silliness, but tender moments are expertly handled, while audience participation and slick use of projector screens to visualise surreal episodes all contribute to the show’s overall genius.

Nan, Me and Barbara Pravi, Summerhall, until 27 August, 5.15pm.
