"GS" was the Japanese equivalent of the British "Beat Pop" that was inspired by the first wave of musical groups (Beatles, The Kinks, The Animals, Herman's Hermits)that had dominated the U.S. airwaves in the so-called "British Invasion" in the mid 60s. Just as in the U.S., record labels made a mad dash to secure and market a horde of similar sounding groups, all in an effort to capitalize on the trend. Groups such as the Outcasts, the Golden Caps, The Jaguars, The Beavers, The Dynamites and the Mops scored hit singles for their record labels. The two most popular groups of the time, "The Tigers" (whose lead singer Kenji Sawada later went on to a notable solo career) and "The Tempters" released a number of hits that are still fondly remembered today.
