Final answer:
The question seems to refer to a dance introduced by the British and popularized in America in 1963, during the era of the Beatles and the British Invasion, which influenced American youth and their culture with a backdrop of rock 'n' roll music.
Step-by-step explanation:
The dance mentioned in the question, introduced by the British and brought to America in 1963, was likely part of the cultural wave associated with the Beatles and the British Invasion of music. However, without a specific name given for the dance, it's challenging to pinpoint its exact identity. The cultural context surrounding the British Invasion aligns with the timeline and the notion of rebellion against the emotionalism of rock 'n' roll, as mentioned. Indeed, rock 'n' roll music, which was deeply embedded in the African American rhythm and blues tradition, had already created considerable controversy and generational divides in America throughout the 1950s and early 1960s. White musicians like Elvis Presley brought this music mainstream, much to the dismay of many parents and conservatives who feared its influence. Rock 'n' roll was viewed as a rebellious and, to some, a degenerative force within American society, due to its association with and roots in African American culture and its promotion of values that ran counter to the era's norms.
