To paraphrase Bill Clinton, it's the songs, stupid. More specifically, the clutch of top-flight tunes written by book writer–lyricist Alan Jay Lerner and composer Burton Lane for their problematic 1965 Broadway musical comedy about reincarnation, 'On a Clear Day You Can See Forever.' Those siren songs have lured re-conceiver–director Michael Mayer right onto the rocks in this misguided retooling attempt. Mayer and current book writer Peter Parnell keep trying to jam them into a new story and characters that manifestly don't want them, diminishing the very thing Mayer and Parnell supposedly value. The result is the depressing misfire currently at the St. James Theatre, starring a distinctly ill-at-ease Harry Connick Jr.
