Caryl Churchill's Not Not Not Not Not Enough Oxygen is a short radio play set in a futuristic London. It was first broadcast on BBC Radio 3 on 31 March 1971.
People live in one-room cellblocks in the London of 2010. Outside, the air is thick with smog and thronged with dangerous citizens referred to as ‘fanatics’ who frequently kill themselves and others in random attacks. Vivian, who is married to somebody else, wants to move in with Mick, a man old enough to remember when it was safe to walk around in London, when there were still birds and when you could procreate without a license. Mick yearns for a cottage in the country. Maybe his son Claude, a celebrated musician who is coming to visit after several years, will find it in his heart to help.
The BBC Radio 3 production was directed by John Tydeman, with Barbara Mitchell as Vivian, John Hollis as Mick and Clive Merrison as Claude.
