Here's a breakdown of Howard Ashman's August 22, 1986 workprint of "Little Shop of Horrors," available for viewing at the Library of Congress. The LOC notes it as the "complete workprint with original ending."
Dated August 22, a list of "Additional Shooting to Do" containing shots and scenes intended for the theatrical "happy ending" is dated four days earlier (Aug 18), implying this copy of the workprint was likely made for Howard so he would have a copy of the "true" cut of the film. This is also possibly the cut of the film shown to the second infamous preview audience, if not also the first. However, without a date for either preview, it's impossible to say for certain.
(These are based on my own hastily written handwritten notes, taken at the Library. Notes denoting a cut from a previous workprint has been taken out. Any sequence mentioned with no note should be assumed to be close to, if not identical to, final edit.)
