(Note: Not sure if this is the right place to ask this question, but this link: https://meta.stackexchange.com/questions/300800/where-can-i-ask-questions-about-a-broadway-show brought me here.)
My friend and I were chatting about Miami fullback Larry Csonka the other day (it was a Mystery Science Theater 3000 discussion) and perusing his Wikipedia page I came along this intriguing paragraph:
During the 1971 off season Csonka starred in the critically well received off Broadway play of "Larry Csonka and the Chocolate Factory". Due to financial backing and Larry's contract with the Dolphins barring him from any off season "strenuous activity" the play never gained commercial success, but for his efforts Csonka was nominated in the 1972 Obie Award for best Actor, where he eventually lost to Douglas Rain for his role in Vivat! Vivat Regina!
References to back this section up included Larry's IMDB page (there's no reference to the show on there) and the Obie Awards archives (if you search for 1972 you only get a list of winners).
My question: Besides this mention on Wikipedia, is there any evidence out there to confirm this was actually a show?
