Theatre reviews: Mark Thomas – Check Up: Our NHS at 70 | Where It Hurts

Perhaps it takes a stand-up comedian of Mark ­Thomas’s experience to create a show as perfectly balanced between laugh-a-minute entertainment and hard-edged political commentary as his latest monologue Check Up, designed to mark the 70th anniversary of the NHS. For the past year,­ ­Thomas has been researching the state of the service, visiting operating ­theatres, accident & emergency departments and GP surgeries, mainly around London.
