Well, I have it in hand now and have listened maybe five times, but like you, I thought the way to get it would be to separate the channels, especially where they are doing two songs at once. I loaded it into Sound Forge in preparation for that, but hadn't gone much farther than that.

Just at first glance, it looks like you've done an admirable job, Stewie. I'll see what I can do, also some time before the end of the weekend. I'll also send the song on to a few of the usual suspects for their input.
