FYI, "The Grateful Dead Movie" is on PBS right now in my neck of the woods.
Scott, have you heard that the Dead are now letting people share downloaded MP3s of old shows on the Internet now, as long as no money changes hands? If the MP3s have been done right, I don't think they'd sound any better or worse than the many-generations-from-the-master cassettes that we both know and love from years past. :)
