Jaws (1975)'s 5.1 mix heard on all streaming versions uses a different recording of Man Against Beast from the one in the theatrical mono.
That would be more a subject for this thread…
…but yes you are correct. There was apparently tape damage to the master of the original take so when the film was remixed in 2000 an alternate take was used. The original take was restored for the 2015 Intrada CD however. A shame Universal didn’t bother to restore it to the film for the UHD release last year.
