I'm a bit curious about the changes in plot. I have the 1982 version but i recently went to see a production and "The Hills of Tomorrow" and "Rich and Happy" were cut. I was really disappointed as I thought they were great songs. Anyway, i know there were revisions of the script (I'm assuming because it was a bit of a flop at first) but does anyone know more?
Thanks in advance.
