Imagine reveals the darker side of one of Britain's most original and inventive artists. A sculptor working with found materials, Cornelia Parker creates beauty from acts of brutality - an exploded shed, piles of squashed silver, the charred remnants of a burnt church suspended in time. Born in 1956 to a German mother and an English father in rural Cheshire, Parker always struggled to fit in. Art was her escape. In 2016 she embarked on the most high-profile commission of her career - the roof of New York's Metropolitan Museum of Art. Alan Yentob follows Parker's creative process in a film that sees her delve deep into America's history, cinema and art, as well as her own personal past.

From beatnik to mod, from folkie to disco tart, from glam rocker to, most recently, crooner of American standards, the newly ennobled Sir Roderick Stewart has had a remarkable musical journey. Alan Yentob visits Rod at his homes in Beverly Hills and Essex and talks to his friends and family, including all eight children aged from two years old to 50.

Featuring rare archival footage of Rod when he was barely out of his teens and living above his parents' north London sweetshop, in a revised repeat Imagine examines an entertaining career across five musical decades.
