I figured I'd go ahead and put this list in a separate thread as opposed to it being buried in another one. It's getting really hard to keep track of all these damned bands, but it's a good problem to have.
Sorry about the too-tight formatting...the Forum doesn't seem to allow monospace fonts like Courier.
If there are any errors or omissions, let me know.
