To Play or to Win?
Nearly 650 children entered this year's competition.
Many will dream of becoming a professional musician, but few will even come close to achieving that ambition. Are competitions encouraging these delusions? How should music in schools be taught? Can the ideals of music-making ever be reconciled with the spirit of competition? Professor Alexander Goehr and three distinguished performers, Nigel Kennedy , John Lill and Marisa Robles , discuss these issues and propose novel solutions. Film editor MALCOLM DANIEL Producer DONALD STURROCK

Dear Mr Baker
... you say that the problem with comprehensive schools today is that the quality is not what it should be. Where's your evidence for this, Mr Baker ? I say you're wrong, and I do have evidence. SOUTRA GILMOUR,
Haverstock School
We've heard from the politicians, the journalists, the educationists - but what do pupils think of the massive changes about to take place in state schools? This film gives pupils from three very different comprehensives a chance to demonstrate the quality of education they've had in the state system, and challenge Mr Baker on some of the proposals in his Education Reform Bill.

The most isolated inhabited island in the world is haunted by huge brooding statues and a mysterious past. Science has unravelled some of its secrets, but now, in the second of a two-part investigation, "Horizon" looks for alternative information to solve the remaining pieces of the puzzle.

The islanders believe that the statues literally walked, by magic, from their quarry to the ceremonial platforms. They believe that an old woman's spell on greedy stone-carvers brought the quarrying to a halt, but hazy myth and scraps of legend can be used to re-interpret scientific finds, and finally tell the story of the extraordinary statue-builders.
