Carolling rarely happens in Scotland because the weather stops people from roaming around outside. I sang in a choir for more years than I care to remember and they are always in big demand at Christmas, for shopping centres and concerts. If I never sing another carol again it'll be too soon. However there are plenty choristers still out there. One of my nieces plays the euphonium and has been in various bands for years. She gets together with a group of pals and they go and busk shopping malls, playing carols. They make an absolute bloody fortune at it.
