Picture of Robert Goulet from 1964 - oh be still my fluttering heart! :-)
You know, it was confusing. I did a LOT of Google searching for posters of his Broadway shows. The one I turned up said that he was King Arthur and you note that he was way down in the list of names in that one.
I am in Texas and not familiar with what all he did on stage. Also, I believe the larger poster I found was on page 36 or somesuch on one of my Google searches or I’d find and post the link.
Lol, I just went with what I could find, and as you noted - it may be incorrect. I’m thinking he may have been in Camelot a number of times in various plays??
Heading for bed, night.
