Nightclub Two Step (Nightclub Two-step, NC2S, sometimes Disco Two Step or California Two Step) was 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. 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 Lady In Red.
The Nightclub Two Step basic step can be counted as One & Two - Three & Four -. 
The dance position for Nightclub Two Step is with a more relaxed hold than typical ballroom dances, or "what people tend to do without lessons". The leader rocks back on his left foot, the follower on her right, for one beat. "The toe is to the heel, but not further. Don't twist your hip. If your hip opens up, you have gone too far." A gentle but noticeable resistance is maintained during the rock step. Then both partners replace weight on the second part of the first beat. On the next beat, the leader takes a step to the left and the follower to the right. Then both partners repeat, but on opposite feet (the man rocks back on his right foot and moves to the right).
The quick rock steps should be matched with the quick drum beats in the music. The "slow" drum beat and slow step can occur on either the second and fourth, or the first and third beats of a measure. Although other rhythmic interpretations of the music are possible, including the use of "breaks" in the music, they are beyond the scope of this article.
Side-cross-side. Another pattern in NC2S is the side-cross-side move. Typically, the lead starts this move by stepping side with his left foot and then crosses in front with his right foot. This is followed by another step to the side with the left foot. The rhythm, here, is Quick, Quick, Slow. The follower does the same thing, but starts with her right foot. Both partners cross in front. In an interview with Phil Seyer  Buddy said he created this move by modifying something that was popular in the 60's called the "Surfer Stomp." The surfer stomp was simply, side, together, side, touch. In the DVIDA Nightclub Two-Step syllabus, this action is called a Traveling Cross.
