Well, I have to say, this is the fastest (maybe the only) personal reply I've received from a website like visiteureka.net. The managing editor, Ian Mullen, returned an e-mail within an hour or two, and then another later. To my list, he added one more song, from the episode "Once in a Lifetime." If he's right, there are only three songs, and we've found them. What I called "The Ride of the Valkyries," he titled "Cavalcade of Brunhilde's Sisters;" another name for the same piece (I'll double check). There is still some background music, I think, to be listed, so let me know if you hear something familiar and have, uh, a Eureka moment. Really, the drugs are wearing off, I promise. See list in previous post for udpate.
7.6.07 Confirmed: "Ride of the Valkyries" and "Cavalcade for Brunhilde's Sisters" are the same piece. Thought so. My father liked to mow the lawn to it, but that's another post.
