Trapeze Girl
Reporter Esther Rantzen
Another chance to see three programmes from the award-winning series which allowed talented amateurs the chance of their dreams - to take part in a spectacular professional event.
This week a 17-year-old girl from a children's home, who is an amateur gymnast, trains for the high trapeze. It is the most dangerous act in the circus - many trapeze artists fall to their death. We follow her two months' training, meet the stars of the circus - and then wait to see if she succeeds.
Trapeze Girl put a lump in my throat at times, making me want to cheer.

On one side the sporting superstars, who can cream millions of pounds from the firms whose clothes or equipment they carry on to the - televised - field of play. On the other side the television companies and sports organisations, who are desperately worried that unofficial advertising will drive sport off our screens and eventually out of business.

Judith Hann follows Derby County Football Club, whose chase for sponsorship has already put them in conflict with the television authorities, and Michael Rodd examines the divided interests which threaten to drive sport, as we know it, off our television screens. It's a game in which the rules are changed from year to year, but in which they are broken with remorseless regularity. The television companies are now facing up to the biggest challenge of all - flagrant advertising at the very heart of the sporting action.

The battle will be fierce, and this programme sets the scene.

One of the finest singers of our time in the first of three programmes in which he will be joined by international guest artists. Tonight's guests:
Shirley Bassey , a truly world-class British superstar making a very rare guest appearance and Stan Getz Europe's greatest jazz saxophonist
Orchestra conducted by HARRY BETTS Associate musical director
