Above:
A link to some "musical score cues" for Alfred Hitchcock's 1972 thriller "Frenzy."
These cues were made by the famous musical composer Henry Mancini, who "ruled the 1960s" with scores to the Pink Panther comedies and thrillers like "Wait Until Dark," "Experiment in Terror," "Charade" and "Arabesque." Mancini also did the "jazz thriller" theme for the TV show called Peter Gunn.
In 1971, Alfred Hitchcock hired Mancini to score "Frenzy" but soon fired Mancini and threw out his score ("Too sinister" said Hitchcock.) Ron Goodwin did the score instead.
I LIKE Mancini's score better than the Goodwin score that ended up in the movie.
But in these "Mancini cues" (discovered by MC poster horrorlover656) is one called "Babs Grabs" -- eventually in it you can HEAR: the Jaws theme.
Yep, there it is. Three years before "Jaws" came out and made that theme famous.
I don't think that John Williams in any way "stole" Henry Mancini's UNUSED Frenzy music to create the Jaws theme but:
ONE: "Great minds sometimes think alike" -- two men heard the same music in their minds
AND:
TWO: Let's be thankful that Frenzy didn't use this music. Tens of millions more people saw Jaws than saw Frenzy -- so the music got more famous than it might have been.
