Cockamamy. Adj. Ludicrous or nonsensical. Alice and her granddaughter Rosie are a team. They live together, eat together, watch Countdown together. Until things start to become ludicrous. Nonsensical. Cockamamy is a heartbreaking, hilarious story about companionship that explores the reality of living with dementia. A compelling new play, this sell-out show previewed at The Camden Fringe Festival last year.
