Some online sources give a total of 152 performances for the run. The Best Plays of 1954-1955 and the New York Times gave that number, but Variety and the paper then known as The Billboard both listed 149. We believe both numbers to be incorrect, although 149 is closer.
The production opened on a Wednesday evening. Had it played eight performances each full week of the run, plus five the first week (which is what it did play the first week), then 149 would be correct.
The reason we list 148 is because there was no Wednesday matinee closing week. There was a special Thursday matinee instead, but this was a benefit for the Actors Fund. Actors Fund benefits have traditionally not been counted in performance totals and so we list 148.
