For Bohemian Rhapsody, the Freddie Mercury biopic, 21st Century Fox enlisted the current lineup of Queen to re-record the famous 20th Century Fox fanfare theme with a Queen twist (the finished product can be seen in that link, along with Queen's Brian May recording the reaction of moviegoers seeing it for the first time).
How unprecedented was this on the part of 20th Century Fox? I can't in my memory remember this ever being done before, and the only 20th Century Fox fanfare I've seen is the one I've grown up seeing. How commonly does 20th Century Fox change the fanfare theme to coincide with a movie or special event?
