Task: Question Answering
Input (English): Passage: A significant stylistic shift in the Kinks' music became evident in late 1965, with the appearance of singles like "A Well Respected Man" and "Dedicated Follower of Fashion", as well as the band's third album, The Kink Kontroversy, on which session musician Nicky Hopkins made his first appearance with the group on keyboards. These recordings exemplified the development of Davies' songwriting style, from hard-driving rock numbers toward songs rich in social commentary, observation and idiosyncratic character study, all with a uniquely English flavour.The satirical single "Sunny Afternoon" was the biggest UK hit of summer 1966, topping the charts and displacing the Beatles' "Paperback Writer". Before the release of The Kink Kontroversy, Ray Davies suffered a nervous and physical breakdown, caused by the pressures of touring, writing and ongoing legal squabbles. During his months of recuperation, he wrote several new songs and pondered the band's direction. Quaife was involved in an automobile accident, and after his recovery decided to step back from the band for much of 1966. Bassist John Dalton filled in until Quaife returned to the group at the end of the year."Sunny Afternoon" was a dry run for the band's next album Face to Face, which displayed Davies' growing ability to craft gentle yet cutting narrative songs about everyday life and people. Hopkins returned for the sessions to play various keyboard instruments, including piano and harpsichord. He played on the band's next two studio albums as well, and was involved on a number of their live BBC recordings before joining the Jeff Beck Group in 1968. Face to Face was released in October 1966 in the UK, where it was well received and peaked at number eight. It was released in the US in December and was tipped as a potential "chart winner" by Billboard magazine. Despite this, it managed only a meagre chart peak of 135—a sign of the band's flagging popularity in the American market.The Kinks' next single was a social commentary piece entitled "Dead End Street". It was released in November 1966 and became another UK Top 10 hit, although it reached only number 73 in the United States. Melody Maker reviewer Bob Dawbarn praised Ray Davies' ability to create a song with "some fabulous lyrics and a marvellous melody ... combined with a great production", and music scholar Johnny Rogan described it as "a kitchen sink drama without the drama—a static vision of working class stoicism". One of the group's first promotional music videos was produced for the song. It was filmed on Little Green Street, a small 18th-century lane in north London, located off Highgate Road in Kentish Town.
