When Pina Bausch revived her seminal 1978 dance piece in 2000, she opted to use a cast of seniors, previously untrained in stage dancing, with stunning, if sometimes uncomfortable results. The piece is set in a dance hall, with the participants preparing for an encounter and hoping to find love. Against a background of sentimental German songs of the 1930s, jazz, and tangos, the performers, all aged between 65 and 75, enact mating rituals and sexual frenzy apparently more suited to those less than half their ages.
