TOD:
I was taken to see the movie version of Porgy and Bess at some point in its first year of release, and it was as much of a game changer for me as West Side Story would be a few years later. I played the soundtrack LP to death, later followed by the Price/Warfield recording. I bought the Duke Ellington, Mel Torme/Frances Faye recording, and in those years I wasn't so interested in jazz arrangements but I'm very glad I took good care of that copy and still have it. Later, the Lehman Engel "complete" recording became an obsession.
As for seeing it performed, one of my great regrets is not being able in the mid-1980s, when I was living and working in L.A., to get to NYC to see it at the Met. That first Saturday broadcast was the greatest thrill, even though it was hampered with transmission problems. My cassette tape of it is probably fair, at best. I should see if it still plays and back it up to digital. I've seen a few productions that ranged from fair to middlin', and I'm afraid I passed on the Broadway incarnation a few years ago. Haven't watched the Trevor Nunn either, as of yet.
