As of 2001, no member of The Tavistock Society had ever met Dan Ackroyd. This all changed one day in Sainsburys. As he absently placed another aubergine in his basket, one quick-witted member of the Society realised the potential monetary value of such a celebrity-touched artefact. The ensuing fracas saw us banned from the premises for the duration of the year. The artefact remains in our HQ.
