Those who have memorized every known lyric to “You’re the Top” will find a lot to quibble about with this five-disc salute to the Great White Way, “Broadway: The American Musical.” Where’s “Lady in the Dark,” “The Cradle Will Rock” or “Sweeney Todd”? But those folks are missing the point. This handsomely packaged, impressively annotated collection—a companion to the PBS documentary of the same name—is intended for those who just want to hum the tunes. A sprinkling of rarities, such as Bert Williams singing “When the Moon Shines on the Moonshine” from “Ziegfeld Follies of 1919,” won’t make this a must-have for show queens. But for those who haven’t heard “A Chorus Line” since they played it on their parents’ turntable, it will be one singular sensation.—MS
