Bush wrote this song for her dance teacher Lindsay Kemp. It's about how a person discovers free expression.
The inspiration for this song came also from whales. Kate thought that they were graceful and sang beautifully. Whale song is heard at the opening of the track.
While "Wuthering Heights" was the first single from Bush's debut album in the UK and most of the world, this song was the first released in Japan and reached #1 in that country. Oddly enough,it did not chart anywhere else.
