Boys dared to grow their hair and girls dared to wear mini skirts and in Korea indecency officers patroled the street with scissors and rulers, publicly cutting hair too long and checking if skirts were too short. Shin Joong-hyung, was there with his 70s hit, Beauty, as were other musicians and artists like Sanullim and the Key Boys. Shin's memorable hook from "Beauty" of "I look at her once, look at her twice, I want to keeping looking at her” matched with an addictive beat and guitar riff created the trend of "I _____ once, _____ twice, I keep wanting to ______" wordplay according to Jishik Shidae's E documentary on Shin (link to part two, giving video clips, photos and some of the music from the time). Shin was performing since the 50s, beginning his career entertaining US troops, and in the 60s in bands like Add4 and he continued to pump out popular hits that are still familiar to the ears of many Koreans today.
