The performers were all very good! Mark Jacoby and Gregg Edelman were the two uncles. Walt (the kid), played by Johnny Rabe, had also played Ralphie in the Broadway run of
A Christmas Story, which also started at The 5th Avenue. The two guys playing the uncles as young men were quite good, too. Kevin Earley played the younger version of Mark Jacoby's character, but I don't know who played the younger Gregg Edelman. I don't have my program with me and the cast list is not on 5th Avenue's website. Jenny Powers as the princess (I forget her character's name...it's different that what's used in the movie) and Kendra Kassebaum as Walt's mother were well cast. I read the synopsis of the movie and it seemed like she was supposed to be manipulating the kid from the beginning. I didn't get that sense in the musical, at all. It really did seem like she was genuinely just leaving Walt with the uncles so that she could go to business school (or whatever kind of school it was). She did tell Walt to look for the money, but to me, that seemed more like an afterthought, not a real plot device. But it was a minor detraction (and only after reading the movie synopsis).
Otherwise, a very good time was had by all.
