No, Finian's Rainbow remained quite faithful to the stage version. No songs were cut and replaced with new ones, and the plots and subplots were retained. Some allowances were made so Astaire could sing and dance as Finian (which the stage Finian didn't do), but otherwise it's not really comparable to Paint Your Wagon. It also didn't lose money: it was produced economically and did well enough to be classified as a hit.And which bucket would Finian’s Rainbow fall into? Isn’t that similar to PYW in that it’s a 1947 stage hit retrofitted for the revolutionary 60’s audience.
