The seismic arrival of rock ‘n' roll jolted postwar teenagers onto their feet, first in America and soon around the world. Punchy soul and R&B cuts also drew youths to the dance floor in record numbers, while infectious hits like “La Bamba” and “Tequila” imported exciting new flavours from Mexico. Doo-wop's influence on the era was felt in close harmonies and compact love stories, even as clean-cut pop singers turned to Italy and beyond for fresh inspiration. By the time explicitly body-moving tunes like “The Twist” came along, there was no stemming the tide of liberated limbs.
