George Melly presents films of the greatest names of swing jazz - but with a difference. Some were made for visual juke boxes which flourished in the early 40s, others are promotional shorts from the major Hollywood companies. The forerunners of today's rock promos, these gems are by turns witty, moving, surreal and always irresistibly entertaining. The line-up includes
