"Changes" is a song by David Bowie, originally released on the album Hunky Dory in December 1971 and as a single in January 1972. Despite missing the Top 40, "Changes" became one of Bowie's best-known songs. The lyrics are often seen as a manifesto for his chameleonic personality, the frequent change of the world today, and frequent reinventions of his musical style throughout the 1970s. This single is cited as David Bowie's official North American debut, despite the fact that the song "The Man Who Sold the World" was released in North America two years prior. This is the last song Bowie performed live on stage before his retirement from live performances at the end of 2006.
