Communal singing is probably one of the oldest forms of human activity, (apart from the more obvious biological habits, that is!!) for recreation and building and sharing identity and relationships. I have experienced what feels like an almost primal shiver when something special happens between people at a singaround.

And the point made about the negative impact of "Broadcast Quality" is an excellent one. My OH has a lovely baritone voice but he is convinced that he cannot sing, because he was told this for years. Going to singarounds is a gentle and supportive way to help people find their voice, and to have fun sharing, learning and harmonising together. I agree all the points about needing a skilful MC in order to get the balance right, but singarounds can be very special indeed.
