"Uptown Girl" is a song written and performed by musician Billy Joel, first released in 1983 on his album An Innocent Man. The lyrics describe a working-class "downtown man" attempting to woo a wealthy "uptown girl." The single peaked at #3 on the Billboard charts in the US, and #1 in the UK, staying at that position for 5 weeks; it was the second biggest selling single of 1983 in the United Kingdom behind only Culture Club's "Karma Chameleon", which Joel had knocked off the number one position on November 1, 1983; in 1988, Rolling Stone ranked "Uptown Girl" #99 on their list of the 100 most important singles of the period 1963-1988. The song was the 19th biggest selling single of the 1980s in the United Kingdom.
The style of music, including the doo-wop beat, the close harmonies and Joel's use of falsetto singing, is reminiscent of Frankie Valli and the Four Seasons. The song also has the uncommon feature of changing key from the original two times before going back, for a total of three keys.
