577 days ago - “Legally Blonde,” the new musical, begins with a song called “Omigod You Guys” — and it’s one of the two best tunes in the show. Rodgers and Hammerstein (or their estates) don’t have much to worry about. Still, the joie de vivre spirit of that tune remains throughout the show’s two and a half hours, and it’s that tone that makes this lightweight story of a not-so-dumb sorority girl who “finds herself,” by way of Harvard Law School, so appealing.
