Neil Diamond released Sweet Caroline in 1969, and it became one of his most enduring hits, largely because its chorus invites audiences to sing along. The song gained a second life as a stadium anthem, most famously at Boston Red Sox games at Fenway Park, where fans join in during the eighth inning. From there it spread through karaoke bars, weddings, sports broadcasts and social videos, becoming shorthand for a shared, upbeat celebration. Its simple melody and communal chant keep it instantly recognisable across generations.
