Glittering balls hanging from the ceiling, electronic beats and/ or a strong bass and people dancing.
That's what most people, including me, think of when we hear the word "disco". But in my mind, there is another thing which I'm sure won't pop into the mind of people who are unfamiliar with Bollywood: the disco song-and-dance.
The disco song-and-dance assumedly made its way into Hindi film tradition in the 70s, especially after the superhit Disco Dancer, and was very popular in the violent/glittery cinema of the 80s and 90s. It also appeared in a lot of more or less commercial films and especially the big blockbusters of the early 2000s, representing the "new, modern" youth. It also found its way into a few more independent productions and also some more recent films, but is currently only seldom seen in films, as the disco background-song has been gaining popularity. At the same time, film parties have moved away from discos and now often happen elsewhere.
In a disco song-and-dance, all the three elements I named to start with are included, but what defines the disco song is that a) people sing a song themselves, and b) a bunch of people dance to the same choreography.
