I think the WI tends to be stronger in rural areas (like darkest Salop for instance). We were singing at their Xmas do and it was real good fun. I have an abiding memory of two elderly and frail-looking ladies standing up waving their headscarves, a la soccer crowd, during a spirited rendition of 'Goodnight Irene'. They had previously almost collapsed during the aforementioned Bobby Polly Matterbe song!
