Sue Beckett, chief executive of Portsmouth Music Hub, was delighted by the event and said: '˜BBC Music Day was a fantastic occasion, and our city's opportunity to tell the rest of the country that the cultural community in Portsmouth is thriving.'

She added the whole event was an important one for the children involved.

'˜BBC Music Day brings together musicians and performers from all over the country to celebrate the impact that music has on all our lives and the power that music has to unite communities,' she said.

'˜I know that the BBC were delighted to be filming our special concert with YolanDa Brown, and they were particularly pleased to be part of our One World environmental campaign.

'˜We all know that music has the power to change lives, and if in the next year our music has the power to change the way young people engage with their environment then we'll have made an impact that may last a lifetime.'
