Staff from McCarthy and Stone in Norwich joined the Invidia Voices choir for a singalong in aid of the Royal Voluntary Service.
The Sing Your Heart Out event at Waitrose in the Eaton Centre, Norwich, raised more than £100 for the charity.
The event was one of many across the country marking McCarthy and Stone's 40th anniversary and raising money for the older persons charity.
Cheryl Bissett, regional sales and marketing director at McCarthy and Stone, said: 'The event was a huge success - the choir was in fine voice and it was great to hear everyone joining in with a fantastic repertoire of festive favourites.
'It really was an uplifting afternoon, and it was wonderful to be able to show our support for Royal Voluntary Service in this way.
'McCarthy and Stone is dedicated to enhancing our homeowners' lives, so it made perfect sense to support a charity during our 40th year which shares our values.'
