Wattisham: Military Wives Break Record
Some of the Military Wives Choir from Wattisham in Suffolk have helped set a new world record for being part of the biggest music video shoot ever.
The women from Suffolk were joined by more than 600 other military wives and choir master Gareth Malone to mark the launch of their new album.
The wives assembled at Wellington Barracks in London to launch Stronger Together which features renditions of tracks such as Take That's Rule The World. The album features choirs from as far away as Germany and Cyprus and two of the tracks feature 760 members of the combined ensembles which now number 50.
Malone - awarded an OBE in the Queen's Birthday Honours in the summer - has also been made the first patron of the new Military Wives Choirs Foundation, set up to support a growing network of choirs on military bases.
