In the program for this original incarnation of the show, there were no individual character names assigned to the actors. There was a large group of character names listed above the cast list, but the cast list itself did not any assign of those names to the cast members.
When the production moved, with the cast intact, to a commercial Off-Broadway run within a month of the first performances at Judson Memorial Church, character names were listed for the actors. None of those characters names were among those in the program at Judson.
At Judson, In Circles was presented on a double bill with a play called Big Projects, I Suppose, by Alex Kemeny.
