You’ll worry at your hunger to keep on reading, but you won’t be able to stop.—Guardian, Book of the Year

The rock'n'roll legend of David Litvinoff is given its definitive account. A considerable work of detection and human sympathy unpicking old myths and making them new.—Iain Sinclair

This surely has the most startling beginning of any biography to be published this year… Vivid, engrossing… Pim gives an all too graphic picture of the seedy 1950s… He is compassionate and humane at every moment. His prose is always careful and stylish.—Richard Davenport-Hines, Guardian

Blending pop culture, social history and interviews with raddled survivors, Pim reconstructs every scene in Litvinoff’s twisted history… Jumpin’ Jack Flash provides the missing piece of Swinging London’s social jigsaw.—Dominic Green, Literary Review
