My Fair Lady -- Diablo Light Opera Company celebrates the fiftieth anniversary of the classic Lerner and Loewe adaptation of Shaw's Pygmalion with a handsome production helmed by Dianna Shuster. All the favorites from "I Could Have Danced All Night" to "On the Street Where You Live" are exceedingly well sung, the sets and costumes are terrific, and there are some fine dance numbers -- all the perks of a world where the entire marketplace bursts into song at the drop of a top hat. Not as much attention is given to the humor and heart of the play, so the viewer winds up paying as little mind to the plight of poor Eliza Doolittle (Angelique Lucia), bullied into ladylike poise and diction, as does her imperious tutor Henry Higgins (John Hetzler). With a little bit more theater in this musical, it'd come closer to adding up to the sum of its parts.
