On July 15, 1989, Pink Floyd performed for more than 200,000 people in the romantic setting of Venice at a concert that was described by press as a “Night of Wonders.” Framed in the foreground by the city’s famous twin columns of its patrons — St. Mark the Evangelist and St. Theodore of Amasea — and in the background by Andrea Palladio’s San Giorgio Maggiore, the band performed from a floating platform in the middle of the Venetian lagoon. “Pink Floyd: Live in Venice” marks the first time an authorized broadcast of the restored and remastered version has been scheduled. The special premieres Sunday, Mar. 1 at 9:30 p.m.
