"I vaguely remember being freakishly close to the stage and utterly falling in love with the very young Mr. Garber."
Do you mean the Mr. Garber who turned 40 a couple of weeks into the run?
Having said that, at the moment I feel like I was very young when I was 40, even though it was more recently for me than it was for Mr. Garber.
I saw it late in the run with some replacements. Garber was gone, replaced by the late Patrick Quinn (how sad it is to say that), and I probably saw Chris Callen, Wendy Makkena, and Jane Summerhays (replacing Feldshuh, J. Smith-Cameron, and Caroline Lagerfelt, respectively).
It was fun, but the play itself probably isn't one of the great farces. Bosco (who is not one of my favorite actors, though I like him pretty much) was really wonderful and he made his scenes fly. When I saw it, the rest of the cast was somewhat in and out, but good enough that it was a fair amount of fun.
Btw, the original production was in London.
