Among the welcome sounds of silence in September in Oak Bluffs, the ones I miss most are the songs played on the 1921 Wurlitzer band organ at the Flying Horses. It was called the Carousel until previous owners, the Turnell family, renamed it the Flying Horses in the 1940s. They chose this in a paean to the one in Watch Hill, R.I., where horses suspended from chains fly outwardly as it goes around, compared with ours; a platform carousel with stationery horses.
