Children, tutors and friends of the Sistema in Norwich programme will be entertaining shoppers at Sainsbury's in Queens Road, Norwich today and tomorrow.

Most of the 120 children involved in the programme are set to take part on the two days, between 10am and 4pm.

Sistema in Norwich, which aims to transform the lives of young people through music, works in the Larkman and Catton Grove areas of the city, offering children the chance to learn a musical instrument and play in an orchestra.

Marcus Patteson, programme director, said: 'The children are singing and playing instruments.

'They are doing it in shifts as it's tiring playing for several hours.

'We have got strings and percussion today and wind and brass will be here tomorrow.

'The feedback from shoppers has been great. One woman was nearly moved to tears. It is also our first big fundraising event so we are collecting at the same time.'

Last week the store launched an instrument amnesty in aid of Sistema in Norwich, which is its charity of the year.

People can take unwanted instruments to the store's customer service desk.
