I had the misfortune of seeing this last week and was filled with relief when it was over. God Bless Michael McCormick, who is far too talented to be in junk like this, for attempting to put over his material with some brio and panache.
The rest of it slogs along lifelessly towards Joyce's funeral which also opens the show. The tagline for the musical is some crap like "the greatest love story you've never heard" (all references to fart love letters and soiled panties have been nicely washed away). Even if this statement were true, Himself & Nora does nothing to make the case for it. You will learn less about Joyce's career and personal life than you would from skimming his Wikipedia page, which I'm convinced is the extent of the research Jonathan Brielle (book, music & lyrics) did for this piece. Other than mentioning Ulysses and Ireland this really could have been about any author/artist who ignores his personal relationships in favor of his obsession with writing. It's George and Dot without any of the nuance or emotion.
The low point is an extraneous number for Joyce's two children in act two that grind the complete show to a halt.
The actors give it their all. Sure, some of them struggle to hold their Irish and Italian accents more than others, but the blame lies with the writing and direction (drab and lifeless).
In short: spare yourself and don't go.
Marie: Don't be in such a hurry about that pretty little chippy in Frisco.
Tony: Eh, she's a no chip!
