One of the most memorable images of the book, Cathy's ghost at the window inspired Kate Bush's Wuthering Heights, which she released as her debut single in 1978. The song includes the lyrics  

I'm so cold, let me in your window

which reference Lockwood's nightmare and Heathcliff's subsequent anguish.  It also tells the story of Cathy and Heathcliff's tumultuous relationship with lyrics such as

I hated you, I loved you too

The song reached number one in the UK singles chart, where it remained for four weeks.
