I dunno, Genie-

Even Steve Goodman sings "passing towns that have no names"....I checked both studio and live recordings, and it's clear he sings "towns."

As for "Summertime," I question you there also. I checked "Summertime" in a book called Reading Lyrics, by Robert Gottlieb and Robert Kimball. This book, which is usually a very reliable source, has "spread your wings and take to the sky." I checked an Ella Fitzgerald-Louis Armstrong recording. Louis sings "take to the sky." Sinatra sings "take to the sky," too. It's not quite clear what Billie Holiday sings on that line (and it's possible she sings it your way), but it's clear that Nina Simone sings "take to the sky."

I listened to about eight recordings of "Song for the Mira," and all say "princes and kings." I'd agree with you that "princes and kings" is correct.

I think you should re-check your sources on the other two songs, Genie.
