I could not tell reading the article if Jones et. al. initial inspiration was a "love of opera" or whether it was just an interesting new challenge/storyboard. It sorta read as the latter, but my hope is that the former was the starting point. This story is very on point today as Mamdani is providing tens of thousands the opportunity to go to the Met -- hopefully each and every one would not have had this opp without M. That is going to be interesting.
Interesting anecdotes to follow if you want to continue...
When I worked in Portland late 80s Coffee People was just one store in the NWest district. Went there every morning for a coffee. They played lots of non-opera, non-classical Muzak. I suggested that perhaps they might consider adding an Opera highlights CD (no streaming then) into the mix. Surprisingly one day I go in and Opera was playing. A few weeks later Opera was playing again, and the barristas were silently singing along with the lyrics when a climactic passage was playing. Made me laugh. Then late 90's I again go every morning to an independent coffee shop this time in Corvallis. Told the owner who was the barrista that I would gift her a CD if she would play it occasionally. She agreed, and I gifted her Cecilia Bartoli singing Rossini's Heroines (a favorite). A while later the owner told me she was going to move to Australia. Asked her if the Rossini was going to be left in the shop, and she said it was going with her.
Edit: Just re-watched the original. I literally remember watching this on TV when it debuted. Anyway... did not know then, but do know now that Mel Blanc did all the voices. In this one Mel's singing. What a unique talent. Studios have tried to replace him, but all efforts fall short. A once-in-a-lifetime talent who most folks enjoy, but know nothing about.
