The list of musical numbers in the opening night playbill did not list performers for the numbers, but the list in The Best Plays of 1962-1963 did list performers. In our list of musical numbers on the main page for the production, we include the additional information from Best Plays, although it may have come from a playbill listing from the production's preview period and not have been entirely accurate by opening.


Some sources given the opening date for this as having been May 14, 1963, but that is incorrect. The production was originally scheduled to open on the May 14, but during its Broadway preview period, the opening was delayed to May 16.
 
Some sources state that the production played three previews. This is also incorrect. Previews started on Tuesday, May 7, 1963. There were evening previews that week Tuesday through Saturday, along with a matinee on Saturday but no matinee on Wednesday. By Saturday, May 11, the decision to postpone the opening till Thursday had been announced. There were previews on Monday, May 13 (originally expected to be the last preview) and two previews (matinee and evening) on Wednesday, May 15. There was no performance on Tuesday, May 14.

In the playbill, there was a list of individual segments, with a cast list for each. On the next page, there was a separate list of musical numbers. Here is the list of segments and the cast list for for each:
