I CAN play in any key but I'm a lot more comfortable in certain ones. As Rory says many licks are much more natural in certain keys.
Bill, our friend Richard Wells (who also happens to be blind) can play MORE than adequately in any key. He has perfect pitch and I don't believe he is capable of hitting a wrong note. When I worked with him, I didn't have to tell him what key I was going to be in, just which instrument I wanted him to play. He is amazing on keys, sax, clarinet, flute, harmonica and BAGPIPES. Last I heard he was learning guitar also.
Rory reminds me so much of Richard except Rory is way past him on guitar. They actually both sound a lot alike on vocals.
For the rest of you, Richard has two brothers, Charles and Talmadge. All three are just about equally talented. Talmadge's best instrument is probably guitar.
Bill sorry to hijack your thread but here is something you'll find interesting about our local music scene and its roots, including info about the Wells brothers and our friends Nita Lynn, and son Robin Vosbury. http://www.thebestoftimesnews.com/article.php?article=91&issue=
