Nightclub two step (NC2S, sometimes disco two step or California two step) is a partner dance initially developed by Buddy Schwimmer in the mid-1960s. The dance is also known as "Two Step" and was "one of the most popular forms of contemporary social dance" as a Disco Couples Dance in 1978.[1] It is frequently danced to mid-tempo ballads in 4
4 time that have a characteristic quick-quick-slow beat. A classic example is the song "The Lady In Red".
