I am tipping this on the basis that Mike Bartlett, who wrote 13, is the playwright.

Love, Love, Love by Mike Bartlett
27 April to 2 June 2012
Jerwood Theatre Downstairs, Royal Court
1967. Kenneth and Sandra meet, and it’s a whole new world.
A fiery relationship is sparked in the haze of the 60s, and charred by today’s brutal realities.
From passion to paranoia, Love, Love, Love takes on the baby boomer generation as it retires, and finds it full of trouble.
By the way, the cast is AMAZING!
