Spirit of the West frontman John Mann, who suffers from Alzheimer&#x27;s, performs his final concert in Vancouver, Saturday, April 16, 2016. Mann&#x27;s wife Jill Daum, who wrote the play Forget About Tomorrow, about a family coping with the disease said, “The story is fictional but it was certainly inspired by what I learned from living with John. What I learned as a caregiver and what I’ve had to watch him go through.”
