My partner Kate Barfield runs two singing groups, the Loudmouth Women and the Clay Chorus(mixed sex). No auditions, anyone welcome.I sing with the Clay Chorus once a week, and it's terrific. For a couple of hours, we are all laughing and enjoying chords and just having fun of a very beautiful kind. Brilliant organisations, and so good for people. Brian Eno's article is excellent, he highlights the benefits very well.
