Mozart's Requiem Introduced and conducted by Roger Norrington
Mozart died in December 1791, leaving the Requiem unfinished. Completed by one of his pupils, it has been the subject of controversy ever since. By going back to Mozart's original incomplete manuscript and 18th-century documentary evidence, ROGER NORRING TON shows how he tries to re-create an authentic style of performance.
The complete performance of the Requiem was recorded at the Church of St Mary-Ie-Bow, London. Meryl Drower (soprano)

Tonight: New Sense of Realism?
For all the immediate discomfort that the present recession has brought to British industry, the Prime Minister has hailed it as the dawn of a new sense of realism - for shop floor and managements alike. But to have any lasting benefit the recession must transform our notoriously low rate of productivity. Are we really on the road to competing effectively in the next two decades?

A TRANSWORLD INTERNATIONAL production

starring Ben Gazzara
The day after he has made the final payment on his Los Angeles strip club, manager Cosmo Vitelli gambles at another club and finds himself heavily in debt to the local gambling mob. Soon the pressure is on Cosmo to pay up promptly, lose his club to the mob, or do a small favour for them-the killing of a Chinese ' bookie '. Ben Gazzara excels as the manager whose illusion of being in full control of his destiny is slowly and cruelly shattered, in one of John Cassavetes 's most brilliantly directed films.
