There are a couple of lady singers from the Taunton area called Yvette Staelens and Michelle Hicks who are known as Roots Quartet, they recently did a sort of presentation using source singers material from that area called Somerset Sisters. They have beautiful voices and I am sure would be happy to help, they also have a CD. If you type Roots Quartet into your search engine, you should find them, they have their own website. Good luck!
