Best known in the U.S. for their hard rock material, Golden Earring have been the most popular homegrown band in the Netherlands since the mid-'60s, when they were primarily a pop group. The group was founded by guitarist/vocalist George Kooymans and bassist/vocalist Rinus Gerritsen, then schoolboys, in 1961; several years and personnel shifts later, they had their first Dutch hit, "Please Go," and in 1968 hit the top of the Dutch charts for the first of many times with "Dong-Dong-Di-Ki-Di-Gi-Dong," a song that broadened their European appeal. By 1969, the rest of the lineup had stabilized, with lead vocalist and multi-instrumentalist Barry Hay and drummer Cesar Zuiderwijk. They experimented with their style for several years before settling on straightforward hard rock initially much like that of the Who, who invited them to open their 1972 European tour.
