PF was set to do what would eventually become “The Pros and Cons of Hitchhiking”.
Then came The Falklands War, and of course Roger just had to drop that to attack Thatcher again. She was one of the “Pigs” on Pigs (Three Different Ones).
By “PF,” you mean Roger Waters. Wright was already out, Gilmour was already fuming at his lack of involvement in the creative process. The Pros and Cons of Hitchhiking was also terrible.
