ABOUT 90 pupils are involved in staging Grease, the musical that proved a film box office hit for John Travolta and Olivia Newton John.

The end-of-term production has been a means to an end for many of the cast and stage crew at King's Manor School, Middlesbrough. For some pupils, Grease forms part of their studies for a General National Vocation in the performing arts - the first time the school has offered the qualification. The youngsters take to the stage tonight and tomorrow.
