 In the DVD commentary, Carrie Fisher (qv) relates that during some  of the London filming, she stayed a house rented from  Eric Idle (qv). Idle and the Pythons were filming  _Life of Brian (1979)_ (qv) at the time. One evening, Idle had a  small party, including Harrison Ford (I) (qv) and  The Rolling Stones (qv), and served a potent liquor (which the  Pythons had been distributing to extras on their film, to help boost  morale) that he referred to as "Tunisian Table Cleaner". They stayed  up most of the night drinking and having fun. The first scenes shot  the next day were the arrival at Cloud City, which she says helps  explain why she and Ford were so happy in those scenes. Idle is said  to be pleased that he had a small hand in how the finished film  turned out.
