What does it mean to sustain a creative life over fifty years? Split Britches: Fifty Years On offers an intimate look at the enduring collaboration of Peggy Shaw and Lois Weaver, the artists behind the groundbreaking performance troupe Split Britches. The collection highlights Split Britches' enduring queer and feminist legacies, tracing how their distinctive butch/femme lesbian aesthetic and collaborative performance practice have evolved over five decades and nearly thirty original productions. It foregrounds their shift toward increasingly autobiographical and introspective work, while also situating their later performances within key theatrical, historical, and critical frameworks-paying particular attention to issues of embodiment, aging, the archive, and queer temporality. Bringing together performance scripts, candid interviews, production photos, accessible essays, and video documentation, Split Britches: Fifty Years On demonstrates how Shaw and Weaver pull from the past in order to critique the present. For scholars, artists, and students, the volume's unique combination of primary texts, critical essays, and multimedia resources makes it an essential volume that considers theatre scholarship and practice, queer and feminist discourses, and the evolution of creativity with age and time.
