Written by Bush when she was just 18, the song’s lyrics are based on the story of the novel of the same name. Kate Bush was inspired to write the song by the last ten minutes of the 1970 film version of Wuthering Heights. She then read the book and discovered that she shares her birthday (July 30) with Emily Brontë. Bush reportedly wrote the song, for her album The Kick Inside, within the space of just a few hours late at night, looking to the moon through her open bedroom window for inspiration.
