John Lloyd and Romesh Ranganathan this week are joined by criminologist and documentary maker Roger Graef, Great British Bake Off judge Prue Leith, and former curator of The Museum of Curiosity Phill Jupitus.

Phill Jupitus, comedian, poet and curator of the Museum's seventh gallery, offers up a Susie and the Banshees concert at Chelmsford Odeon on Sunday 26th July 1981, which featured support from John Cooper Clarke and an animated version of Alfred Jarry's play Ubu Roi. He donates it because of the variety of performances, which inspired Phill to take up poetry.

Roger Graef, criminologist and documentary maker, who has covered subjects like the prison service and the EU, donates the theory of deterrence, the idea that the longest a prisoner is sentence, the less likely they are to commit a crime after they get out. All the evidence shows however that the exact reverse is true, and that we need to think again about the best way to rehabilitate offenders.

Prue Leith, who has run her own Michelin star restaurant, is a novelist, and is to be a judge on Channel 4's Great British Bake Off, gives the Museum the world's first celebrity chef, Alexis Soyer. He invented the caffettiera, the first hot-air powered spit, and created a soup kitchen in Ireland during the potato famine.
