re: Revival Cast Recordings Worth Buying.
I'd get the Broadway recording of "Little Shop of Horrors" if you want something that has the music the way it's done in the show and has all the songs. Get the Off-Broadway recording if you want more feeling in Seymour and Audrey (but don't expect much from the Off-B'way Dentist; he's very boring and during "The Meek Shall Inherit" they didn't record him as Mrs. Luce and he didn't change his voice for Bernstein and Snip).
