Play of the week: A Day in the Death of Joe Egg, various venues

It's difficult to see that attitudes to extreme disability have improved much since Peter Nichols first wrote his groundbreaking black comedy, inspired by the experience of bringing up his own brain-damaged daughter in the 1960s.

This heart-wrenching revival is raised to even greater heights by the pacey stream of gags which flow from Nichols's pen to sit alongside the pain. Ralph Little and Rebecca Johnson are a class double act as Bri and Sheila – the couple whose relationship is stretched to breaking point by the bleak reality of their child's disability.
