On this day in 1978 The Grease soundtrack hit number 1 in the USA. Despite being an American film about American teens rebelling against the American culture of the 1950s, the album was also a huge success in the UK where all of the singles except for Greased Lightning peaked in the Top 10 of the pop chart, with “You’re the One That I Want” dominating the number 1 spot for a record-breaking nine weeks, some months before the film had even been released.
