I guess it's okay to mention Curly's death, since it happened during this time period: 1952. It sorta helps out in understanding the chronology of where they were in their personal lives at this time, especially Moe & Shemp. They had to bury their baby brother and that must have been devistating. I've always wondered if you could tell a difference in the way they presented their act after Curly was gone. I know that's kinda weird, but I've always wondered what they must have been thinking, knowing that Curly would never be a part of the act again. He defined that role so well.
But I'm not knocking Shemp! I love Shemp. His shorts defined The Three Stooges every bit as much as Curly's did. Great guys, all. Howard, Fine, Howard and Howard.
