Honestly this would probably be my vote too, if it counts as a version of it. It's not great or anything but not bad, I like the vibes/flute combination. "Summertime" is just not a song that's ever really done it for me, and despite loving a lot of jazz generally speaking, all the jazz versions of it that I'm familiar with (Billie Holliday, Nina Simone, Miles Davis, Charlie Parker) are pretty dull to my ears. I had never heard the Janis Joplin version until reading this thread but that didn't really do it for me either.
