As a longtime fan of the OBC - I saw it tryout in DC when I was a senior in high school (fall of '68) - I was majorly disappointed. The show is about a nebbish-in-a-crowd and a naif, two young cogs in a dehumanizing corporate wheel, the strength of the storytelling the ways these relative kids are exploited. Hayes wasn't entirely wrong, but his comic self-awareness was at odds with the everyman-ness of Chuck. Hayes was something Chuck can't be: cute. And aware of his cuteness. (Jerry Orbach, a character actor, nailed what Lemmon brought to the Apartment: that ordinariness) And Chenoweth was at least ten years older than Fran. Rather than self-present as a poor-ish office worker, she was dolled up in Mad Men drag. The younger Chenoweth might've landed the role with poignancy. But in 2010, at 42 (admittedly passing for 35ish), she was a New York sophisticate, one who burst into "I Say a Little Prayer" a song never in the show, and not really in the lexicon of a girl-woman in over her head It killed the sense of the corporate machinery smother innocents .
That highlights the real problem: the revival was determined to give a singing star more to sing and interpolated songs that added no character information, only chances to express the same emotional states as existing songs. Most egregious, in the already long first act, Chuck exits the party and Fran unnecessarily torches "A House Is Not a Home," a rueful meditation on domestic disharmony that wouldn't remotely occupy the thoughts of a young urban worker - and steals the excavated angst from act 2's "Whoever You Are, I Love You," a less analytical and more personal confession of a young woman involved with a married man. Thus Fran ended up with three songs about her unsolvable-except-by-suicide plight: "Knowing When to Leave" "House is Not a Home," "Whoever You Are," all of which basically covered the same plot turf. She ended up the most emotionally paralyzed heroine in a musical comedy.
Craft was always present in the original - it's Chuck's story - and juking a well told Simon-structured show to serve the Bachrach songbook just added running time. From what I've heard, the interpolated songs cannot be licensed with the show.
