Although widely perceived as untraditional and unpatriotic, Sondheim’s 1991 Assassins is neither; it is in fact based securely on themes and strategies developed within the mainstream tradition of the American musical. In both respects, it shows particular affinity to Rodgers and Hammerstein’s Oklahoma!, a relationship that becomes especially evident when considering the latter’s basis in Lynn Riggs’s Green Grow the Lilacs. The author examines related background, dialogue and individual songs from each musical, the latter including ‘Pore Jud’, ‘Lonely Room’ and ‘People Will Say We’re in Love’ from Oklahoma!, and ‘Everybody’s Got the Right’, ‘The Ballad of Booth’, ‘Gun Song’, ‘Unworthy of Your Love’, ‘Another National Anthem’ and the book depository scene from Assassins. Yet Assassins departs from the mainstream in one important respect: by failing to foreground adequately a sympathetic viewpoint (despite the addition of ‘Something Just Broke’), the show seems to place its dominant characters in opposition to the audience, who represent its real protagonist, the American people.
