A memory play is a play in which a lead character narrates the events of the play, which are drawn from the character's memory. The term was coined by playwright Tennessee Williams, describing his work The Glass Menagerie. In his production notes, Williams says, "Being a 'memory play', The Glass Menagerie can be presented with unusual freedom of convention." In a widening of the definition, it has been argued that Harold Pinter's plays Old Times, No Man's Land and Betrayal are memory plays, where "memory becomes a weapon". Brian Friel's Dancing at Lughnasa is a late 20th-century example of the genre. Source: Wikipedia (en)
