Question for Diehard Elton John Fans, Tumbleweed Connection?

I'm a huge fan of Elton John's album _Tumbleweed Connection_ It's really a progressive rock album based on a Country & Western theme. I want to write a blog on it but I'm having trouble finding a good site to get info on it. Also, was it Elton John or Bernie Taupin who had the idea for the Country & Western theme for the album? IIRC, EJ had a fascination for the old american west and wanted to write a C&W album about it.
