I own a copy of a very interesting book titled 'The Billboard Book of One-Hit Wonders' by Wayne Jancik. The author defines a one-hit wonder as a song that reached the Top 20 in Billboard (an American publication) by an artist who never again made the Top 40. It covers the period from 1955 to 1992. There have been over 700 such one-hit wonders.
