I am of the opinion that everything about the show worked except for a few body-suit costumes that were quickly modified and a few lyrics that might not have been as polished as they should be. Also, I always understood the shape-shifting goddess depicted in each unit to be Califia from Golden Dreams and from The Exploits of Esplandian, even though I know Davison gave her the name, "Eureka", for some strange reason. The whole affair was a solid effort, though, through and through, and it tied the entire park together in a way that gave D.C.A. a coherence, which the park, now, most assuredly lacks.
Incidentally, Michael Eisner also axed the original version of "Steps in Time", which I was lucky enough to see. During employee previews, the show was presented as a gala salute to The Walt Disney Studios from 1928 to 2001. And, the event was really quite impressive, although, if it was made more an historical retrospective with production numbers arranged chronologically, the presentation would have been even better. Before those scenes could be rearranged, though, Eisner got his grubby hands on the show, fired the director, and added the streetwalker/fairy godmother and the two brats, while also demolishing a proscenium that cost the company millions of dollars.
The brain trust in T.D.A. at the time decided, afterwards, to take the electrical parade out of storage and stick the thing in the new park where it just does not belong. I've seen the cavalcade there once, and I have no desire to experience it again.
I would love for "Eureka!" and for a new show like the original "Steps in Time" to be added to D.C.A. And, I would also be happy if the Main Street Electrical Parade, or a new version of that event, returned to Disneyland proper.
D.C.A. really needs to have the various peoples of California represented, and the "Eureka!" festival did exactly that.
