Jazzy, They do change the names he calls Nabulungi...but not just for different locations. The Broadway based production is also constantly changing the names.
The reference to San Fran by the bay in the earlier song, is a set lyric for the song, Two by Two.
I really enjoyed the show when I saw it in NY this past summer. The audience was pretty responsive. I thought it was very, very funny, imaginative and well done. Totally enjoyed myself except for the nagging voice in my head throughout that while this is a really good show, it is not the second coming it's been made out to be.
The danger of big buildup is that few things can ever live up to the anticipation they cause. And that can be a disservice to a really good show. I think I would have enjoyed the show much more if that nagging voice had not been there.
Art has a double face, of expression and illusion.
