Jack I think you are being a bit pessimistic when you say a year I would say about six months at the most. People love travelling to festivals seeing and singing with old friends. Professional performers will not so much 'call it a day' as simply go back to how they started by singing folk songs for the love of it. I've been singing for 45 years and have played most clubs and festivals in the UK, but I am just as happy in a sing around. That said I think you have a point about regular internet appearances. That will not do any harm to the music, and may spark some interest.
