Why would Celtic women performers invoke a dead colonialist English poet in their airs and dance sets? This article provides close readings of Shakespearean elements in the musical compositions of gold- and platinum-selling artists Loreena McKennitt, Ensemble Galilei, and Méav. It assesses the archaicising musical language, structural reshapings, and ekphrastic elements as signals of ‘restitutional creativity’ and trans-temporal collaboration. It also analyses the reception of these works by fans and critics, responses replete with invocations of tradition and of timelessness. Like the fanfic-producing enthusiasts of Johnathan Pope's Shakespeare's Fans, the fans for Celtic music capitalise on their awareness of Shakespearean elements in this music to display personal expertise. In so doing, they enhance their own belonging within the Celtic music community.
