Why did grady replace Fred on Sanford and sons?

Answer 1

Redd Foxx was offered a lot of money to do a variety show on a different network. He left to do that. It was quickly canceled. Redd did an interesting Christmas skit on that show. He was a poor man living in a rundown hotel room on Christmas Eve. He hung two chairs on a coat rack, put a blanket on it, then pulled a string of lights from outside the window and wrapped them around it. When he was done it was a beautiful Christmas tree in a dark room.
