A spokesperson for the Military Wives Choirs said: “Bringing together choirs from across our network to perform together is a perfect example of how our organisation lives our ethos of ‘sing, share and support’.

“Our network is geographically diverse, and we’re thrilled to be performing across the UK in some wonderful venues to celebrate both our charity and the launch of this exciting film and soundtrack.”

The tour is in celebration of the movie, which is directed by Peter Cattaneo (who also helmed The Full Monty), and features an all-star cast including Kristin Scott Thomas and Sharon Horgan.

The film is described as the “inspirational story of friendship, love and support from the home front”, based on the real stories of a group of women who find themselves at the centre of a media sensation – and a global singing movement.
