OK, guys, gimme some help here.
When I was a teenager, my friend had an 8-track copy of "Animals" from PF. This cartridge had a different version of "Pigs on the Wing" than I've heard anywhere else -- instead of the two short bits bookending the other three songs, it was one track stitched together by a lovely slide guitar bridge.
My wife says she remembers someone else having that version way back when. And that's all I can find.
Does this ring a bell? And more importantly, does anyone have an idea of where I might lay my hands on a copy?
This had better not be an instance of "everyone knows this but me."
I've asked a lot of knowledgeable people over the last 20++ years about this, and no one's given me a good answer yet.
