Everything is Hunky Dory for The Kooks

Well David Bowie did release a genre-bending album in 1971 called Hunky Dory. Reviewer Stephen Thomas Erlewine at Allmusic.com called Hunky Dory "a kaleidoscopic array of pop styles, tied together only by Bowie's sense of vision: a sweeping, cinematic mélange of high and low art, ambiguous sexuality, kitsch, and class."

Probably David Bowie himself was saying "everything's cool" with Hunky Dory, as he was about to announce to the world that he was gay and launch into his career-making Ziggy Stardust personna.

Everything was hunky-dory for him. It was the '70s!

The website The Phrase Finder says one of the earliest American uses of the phrase in this way was found in The Galveston Daily News in 1866, giving this advice: "In the morning wash with Castile soap, in soft rain water, and you are all 'Hunky-dore' - as fresh as a lily - as sweet as a pink."

("Hunky Dory" may be of Irish origin, as Bowie's mother was of Irish descent. Perhaps the expression was originally brought to America by immigrants.)

Hunky Dory...saw the partial return of the fey pop singer of "Space Oddity", with light fare such as "Kooks", a song written for his son, Duncan Zowie Haywood Jones, born on 30 May. (His parents chose "his kooky name"—he would be known as Zowie for the next 12 years—after the Greek word zoe, life.) —Wikipedia

(Hunky Dory also contained the near-Top-40 hit "Changes," which has over time become one of Bowie's best-known songs.)

In 2005 Bowie's song title from Hunky Dory, "Kooks," became the band name of a pop/alt/rock group formed in Brighton, England headed by Luke Pritchard and Hugh Harris.

The Kooks third album Junk of the Heart was released in September of 2011 on Virgin Records. They make us happy. Everything is hunky dory!
