A weekend of four shows in the Charles Room as part of the Watford Fringe Festival. Linda Firth and Christine Gee kick off with Sisters Are Doing It (For Themselves) — identical twins with a century of life experience between them, sharing laughs and stories. Mat Smith presents The Middle, a wry work-in-progress about almost middle-age, solo holidays, and bad bisexuals. Paul Richards performs Offgridland, a frantic one-man comedy play about trying to switch off from technology. Scott Manley Hadley rounds out the weekend with Bald Personality Disorder — an alternative set on mental health, hair loss, gender, money, and parenting, featuring sequins, poetry, original music, and an interactive quiz. 18–19 July. Free entry, suggested 16+.
