Jonathan Haze, who played Seymour in the original film, attended the opening, and Welles also received a visit from Martin P. Robinson, the designer of the Audrey II plant puppets used in the off-Broadway production (Robinson is also famous for his puppetry on Sesame Street).
The English dubbing was co-written and performed by character actor Mel Welles, who is best known for his performance in the original film version of "The Little Shop of Horrors".
