KATE MIDDLETON will walk down the aisle of Westminster Abbey to a pitch-perfect welcome, thanks to North-East organ experts.

Craftsmen from renowned organ builders Harrison and Harrison are in the abbey now putting the finishing touches to a right royal repair job.

Over the past two months, parts from the organ’s North side case have been restored in H&H’s workshop in Meadowfield, near Durham City, with the last piece returned to London for re-installation last week.

H&H managing director Dr Chris Batchelor will visit the abbey on Monday to check on progress.

The work is due to be completed by the end of the month, ahead of its first major performance – the wedding of Prince William to Miss Middleton on Friday, April 29.

The project has generated much interest among H&H’s workers, whose predecessors built the organ in 1937 for the coronation of King George VI, who was portrayed in the recent box office smash The King’s Speech.

The firm, established in Rochdale in 1861, was moved to Durham City by founder Thomas Harrison in 1872.

It has since worked on organs for Durham, Salisbury and Ely cathedrals, along with King’s College, Cambridge, and many large parish churches, gaining a reputation as one of Britain’s foremost organ builders and restorers.

Experts recently finished building an organ for Bury St Edmunds’ Cathedral, which is due to be unveiled today.

Other projects include repairing the organ for London’s Westminster Central Hall and the Royal Festival Hall. With more than 50 staff, an annual turnover of £2.5m and bookings until 2015, the firm’s future looks sound.

Dr Batchelor, who took over in February, having previously been head of London College of Music, said: “I’ve played a lot of H&H organs and I’ve admired the skill and artistic vision for a long time.

“It’s a firm with fantastic international credentials. I want to maintain the H&H values, which are very high quality instruments with a real sense of artistic profile.”

The firm will begin celebrating its 150th anniversary in October, with bosses planning workshop tours and a touring exhibition.

Miss Middleton may have many things to worry about ahead of her big day but, given H&H’s involvement, wedding music need not be one of them.
