 The idea for a third edition was pitched by MGM/UA Home Video head  George Feltenstein to then MGM/UA president Alan Ladd Jr. (qv)  Feltenstein had typed up a list of musical numbers for a potential  third movie back in 1976 after returning home from  _Thats Entertainment, Part II (1976)_ (qv). Ladd approved the  pitch, but because Feltenstein was a studio exec, he didnt get a  screen credit for his contribution.
