The Military Wives' choirmaster described the group's prize win at this year's Classic Brit Awards as "the candle on the icing of a very large cake".
The choir, comprising wives of Westcountry military personnel, scooped the Single of the Year gong for their Christmas chart-topper Wherever You Are at a glitzy ceremony at London's Royal Albert Hall on Tuesday.
The group helped to round off the evening by performing another hit, the Diamond Jubilee anthem Sing.
They were accompanied by the song's composers, Take That star Gary Barlow and world-famous composer Andrew Lloyd Webber, who both played grand pianos.
Choirmaster Gareth Malone said: "It was very humble beginnings. It is about these women finding a voice and tonight is a great celebration of that."
Members of the choir, made up of the wives and girlfriends of military personnel from RMB Chivenor in North Devon and Plymouth-based 42 Commando, rubbed shoulders with the likes of Sir Anthony Hopkins at the event.
The Oscar-winning actor attended the awards alongside Dutch maestro Andre Rieu, who picked up the prize for album of the year for his interpretation of a waltz Sir Anthony wrote many years ago.
Rieu dedicated the award to Sir Anthony and said: "He is the greatest actor we have now on this planet. Tony, thank you for this fantastic waltz and for your friendship."
