Clive Anderson hosts Maestro's next studio challenge as five famous amateurs with a passion for classical music do battle with their batons conducting the BBC Concert Orchestra.

In the fourth round the students step up to the podium to conduct a programme of popular operatic arias sung by soloists Alfie Boe and Rebecca Evans in front of the panel of expert judges - conductors Sir Roger Norrington and Simone Young, double bassist Dominic Seldis, composer and cellist Zoe Martlew. They must then face the orchestra vote to decide who leaves the competition for good. Show less
