Walking on Sunshine was released in 1985 by British-American band Katrina and the Waves, with lead vocals by Katrina Leskanich and songwriting by Kimberly Rew. It became the band's signature hit and a lasting pop anthem, returning again and again in films, adverts and feel-good playlists. Its short, instantly recognisable chorus makes it easy to lift into short-form video, where a few seconds are enough to set a joyful tone. That combination of nostalgia, familiarity and pure optimism keeps the clip in regular use decades later.
