The Hollies are an English pop group formed in Manchester in the early 1960s. Most of the band members are from throughout East Lancashire. Known for their distinctive vocal harmony style, they became one of the leading British groups of the 1960s and early-1970s. They enjoyed considerable popularity in many countries, although they did not achieve major US chart success until 1966. Along with the Rolling Stones, they are one of the few British pop groups of the early 1960s that have never officially broken up and that continue to record and perform.
