"Hunky Dory" (1971) found Visconti, Bowie's producer and bassist, supplanted in both roles by Ken Scott and Trevor Bolder respectively. The album 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 was known as Zowie for the next 12 years—after the Greek word "zoe", life.) Elsewhere, the album explored more serious subjects, and found Bowie paying unusually direct homage to his influences with "Song for Bob Dylan", "Andy Warhol", and "Queen Bitch", the latter a Velvet Underground pastiche. It was not a significant commercial success at the time.
