Franca Rame: Franca Rame (18 July 1929 – 29 May 2013) was an Italian theatre actress, playwright and political activist.  She was married to Nobel laureate playwright Dario Fo and is the mother of writer Jacopo Fo.  Fo dedicated his Nobel Prize to her.

Raja Rao: Raja Rao (8 November 1908 – 8 July 2006) was an Indian writer of English-language novels and short stories, whose works are deeply rooted in Metaphysics.  "The Serpent and the Rope" (1960), a semi-autobiographical novel recounting a search for spiritual truth in Europe and India, established him as one of the finest Indian prose stylists and won him the Sahitya Akademi Award in 1964.  For the entire body of his work, Rao was awarded the Neustadt International Prize for Literature in 1988.  Rao's wide-ranging body of work, spanning a number of genres, is seen as a varied and significant contribution to Indian English literature, as well as World literature as a whole.

Archangels Don't Play Pinball: Archangels Don't Play Pinball (Italian title: "Gli arcangeli non giocano al flipper") is a 1959 two-act play by Dario Fo.  The play uses the metaphor of a pinball machine—a new innovation in Italy at the time of and one of which Fo and his wife Franca Rame were fond— to convey mechanisation and conspicuous consumption.

Can't Pay? Won't Pay!: Can't Pay?  Won't Pay!  (Italian: Non Si Paga!  Non Si Paga! , also translated We Can't Pay?  We Won't Pay!  and Low Pay?

The Open Couple: The Open Couple (Italian title: "Coppia aperta, quasi spalancata") is a play by Dario Fo.  As with some of Fo's other plays, it is a romantic play which was written with his wife Franca Rame.  It was written in 1983.

In his time he was "arguably the most widely performed contemporary playwright in world theatre".  Much of his dramatic work depends on improvisation and comprises the recovery of "illegitimate" forms of theatre, such as those performed by "giullari" (medieval strolling players) and, more famously, the ancient Italian style of "commedia dell'arte".

Jacopo Fo: Jacopo Fo (born 31 March 1955) is an Italian writer-actor and director.  He is the son of playwrights Franca Rame and Dario Fo.
