When Ziggy played The Marquee Club in Soho, London, in October 1973, most of those invited to the small venue did not realise that this would be the last performance David Bowie would ever give as Ziggy Stardust. Terry O'Neill, celebrated photographer, was given unprecedented access to document the event. O'Neill captured Bowie and his crew backstage as they went through costume changes, and Bowie transformed into the character he'd soon put to rest. On stage, dodging television cameras and lights, O'Neill snapped the incredible stage presence for which Bowie and his crew had become renowned. O'Neill remembers of Bowie: "He became a character on stage. As much as a person takes a role in a play for the West End or on Broadway, learning the lines, putting on the costumes - this was, I think, the way Bowie treated his stage. This night at the Marquee, I witnessed a modern-day Hamlet - and it was Ziggy Stardust". Award-winning music writer Daniel Rachel interviews key contributors of the day, including O Neill, Ava Cherry, Amanda Lear and Geoff MacCormack along with new insights and memories from fans who were in the audience who played witness to this incredible moment.
