Agreed!

Man I've never thought of that before, that would have been something.

Wonder how Dave would have played that bridge solo

All in all, I still think Pigs on the wing separated as they are really play their part within the concept of the album. Even though the extended 8-track version is a fuller song and would have boosted the sales IMO as you said.

See ya, and no one sings me lullabies!
