Wake Up Little Susie was released by the Everly Brothers in 1957 and written by Felice and Boudleaux Bryant. The song tells of a teenage couple who fall asleep at a drive-in movie and worry about getting home late, and its catchy chorus helped it reach number one in the United States. Decades later, its instantly recognisable title and cheerful oldies sound have kept it in films, adverts and short-form videos, where it works as shorthand for a late night, a sleepy morning or a nostalgic throwback.
