"Wow" is a song by English singer Kate Bush. Originally released on her second album Lionheart in 1978, it was issued as the album's second single in March 1979. It was a top 20 hit in the UK. "'Wow' is about the music business," she told her KBC fan club magazine in 1979. "Not just rock music but show business in general. It was sparked off when I sat down to try to write a Pink Floyd song – something spacey." The lyrics include a reference to Vaseline.
