The Bee Gees reached number one on the US singles chart with “You Should Be Dancing,” which reached number five in the UK. The song marked the beginning of their disco era and was used the following year in a scene from Saturday Night Fever in which John Travolta takes over the dance floor. It was also the Bee Gees' first US number-one hit featuring
Barry Gibb's distinctive falsetto. One source calls it the group's second US number-one single, while another calls it their third.
