Kirsty Young's castaway on Desert Island Discs is Lord David Cobbold.

He was just 32 years old when he took over the ancestral pile Knebworth House and he succeeded in turning a crumbling corner of the establishment into one of the best rock concert venues in the world. Over the past forty years, everyone from Led Zeppelin to Paul McCartney to Robbie Williams has played there. The concerts have not only allowed him to keep the house in private hands, but have also given him a front-row seat to some of the most celebrated performances in rock history.
