"You Should Be Dancing" is known today as the first chart-topper in which Barry Gibb uses his now-trademark falsetto (he had previously used it on the top-10 "Nights on Broadway" and on "Fanny (Be Tender With My Love)".

The song was prominently featured in the movie Saturday Night Fever and appears on its soundtrack album. Live performances of "You Should Be Dancing" during the 1979 Spirits Having Flown tour featured the Bee Gees' younger sibling, Andy Gibb, on backing vocals.

This song and the scene from the movie containing the song were seen and heard in the film Short Circuit. Other movies where the song is heard are Donnie Brasco and Despicable Me.

The Boston Celtics also play this song when they are about to win a basketball game accompanied by the ever popular "Dancing Gino" video from the television show American Bandstand. Recently, the Tampa Bay Rays have started playing the song at home games between innings.
