Partially Found?

in This Video with the 30 second version: https://www.youtube.com/watch?v=Ht3C6o52nTc, There is An Interesting Comment from @thechordettesfan1783 here's the comment:

Actually this isn’t the 1974 version I remember. I’m pretty sure this one’s the 1979 version. I remember that one too. But the 1974 version I also remember is like the guy started as a shadow.and looked a little different. He started from far away too. He was walking slower and the explosion was louder. The guys voice was deeper and the music was slower. The music had maracas, I also remember the guy repeating in the background as the beat of “ hate hate hate hate hate hate hate”. And instead of saying “hate hurts you!” The narrator said, “you only hurt yourself!”. That’s all I remember. I did some research and I found another Jewish Chautauqua society PSA and this one has the same voice as the 1974 version I remember https://youtu.be/011IaHapmXw

[UPDATE: Comment Possibly the effect of the Mandela effect]
