Helba Huara: Helba Huara (1900-1986) was a modern dancer from Peru.  Her exotic appearance and unique dance style, which incorporated European and Native American influences, created a sensation in the late 1920s.  Moving from Peru to the United States she became a star on Broadway in the 1927 production of "A Night in Spain".  Later she moved to Paris, and became involved in the artistic and intellectual café society.

The Lockers: The Lockers (originally named The Campbell Lockers) were a dance group formed by Toni Basil and Don "Campbellock" Campbell in 1971.  Active throughout the 1970s, they were pioneers of street dance.  Don Campbell is the founder of the locking dance style, and originally, Locking was called The Campbellock - a style that was based on the dance and song that Don Campbell created.  Toni Basil met Campbell at a club in 1971 and together they formed The Lockers as a dance group.  Toni Basil also served as The Lockers' manager, and was responsible for staging the act.  All the dancers contributed steps and choreography with their unique and individual styles.  By 1975 they were "Dancing their way to stardom" on their own.  Individual members' contributions (as soloist performers) to the dance style and group image coupled with their unique presentation in staging and concept broke down many barriers.  It has been said on the reality dance competition "So You Think You Can Dance" that "The Lockers' emergence on the dance scene changed the face of dance not only for street dancers but for dance in general and has made street dance a true American art form."

This is in contrast to acrobatic, artistic and rhythmic gymnastics, which are sports that employ dance elements in a gymnastics context under the auspices of a governing gymnastics organization (such as FIG) and subject to a Code of Points.  Acro dance is known by various other names including "acrobatic dance" and "gymnastic dance", though it is most commonly referred to simply as "acro" by dancers and dance professionals.

A pom squad slightly differs from a regular dance squad in that it uses pom-poms in all its dance routines, whilst a regular dance squad may or may not do pom work in a dance routine.
