<Li> In the lead - up to the 2016 US presidential election, Simon authorized the use of the song in an ad against Donald Trump . </Li> <Li> In a piece posted by BBC News on May 5, 2017, Simon sings a previously unreleased fourth verse to the song, which she states had been written on a pad some time ago but never made it into the song . It references a man, married multiple times, who "called her once to ask her things she couldn't quite divine". </Li> <P> The song was a number - one hit in the US, Canada and Australia and reached number four in Ireland and South Africa . Bowing at #99 on the Billboard Hot 100 on 2 December 1972, the song took only five more weeks to rocket to the top of the chart, where it stayed for the first three weeks of 1973, also spending two weeks at the top of the Easy Listening chart in early 1973, her first number one on either chart . "You're So Vain" was Simon's breakthrough hit in the United Kingdom, reaching number three on the UK chart on its original release in 1973 . The song was re-released in the UK in 1991 to cash in on its inclusion in a commercial for Dunlop Tyres, peaking at number 41 . </P> <Table> <Tr> <Td> <H3> Weekly charts (edit) </H3> <Table> <Tr> <Th> Chart (1972--73) </Th> <Th> Peak position </Th> </Tr> <Tr> <Td> Australia (Kent Music Report) </Td> <Td> </Td> </Tr> <Tr> <Td> Canada (RPM Charts) </Td> <Td> </Td> </Tr> <Tr> <Td> Ireland (IRE Charts) </Td> <Td> </Td> </Tr> <Tr> <Td> New Zealand (Listener) </Td> <Td> </Td> </Tr> <Tr> <Td> South Africa </Td> <Td> </Td> </Tr> <Tr> <Td> UK Singles (Official Chart Company) </Td> <Td> </Td> </Tr> <Tr> <Td> US Billboard Hot 100 </Td> <Td> </Td> </Tr> <Tr> <Td> US Billboard Easy Listening </Td> <Td> </Td> </Tr> </Table> </Td> <Td> <H3> Year - end charts (edit) </H3> <Table> <Tr> <Th> Chart (1973) </Th> <Th> Position </Th> </Tr> <Tr> <Td> Australia </Td> <Td> </Td> </Tr> <Tr> <Td> Canada </Td> <Td> 8 </Td> </Tr> <Tr> <Td> U.S. Billboard Hot 100 </Td> <Td> 9 </Td> </Tr> <Tr> <Td> U.S. Cash Box Top 100 </Td> <Td> 7 </Td> </Tr> <Tr> <Td> UK </Td> <Td> 35 </Td> </Tr> </Table> </Td> </Tr> </Table>
