Scotty, do you mean me...? You are wrong about me, honestly! Hey, you are the expert in this one!!
Hm, it would be the best to find someone with a DVD of the Porchester recording and to rip a wav from the audio. The problem with mp3 is the fact, if you compress and decompress again and again, the quality gets worse and worse. So, correct me please, if I'm wrong, but if you do an upload of an mp3-sound to youtube, it gets compressed for a second time on youtube. If you catch it from there via a program, it gets decompressed and compressed again for a third time. Every new compression means a loss in quality... One time is ok, but a second and a third...
I have an old Video-Cdr of it, but have never listened to the sound via a proper sound-system, I'm ashamed.
