The excitement, for me, really comes from the vibrant and slightly imprecise passion, which makes it feel larger-than-life in the same way that everything does when you're an adolescent - aided, of course, by the booming atmosphere of Thomas Z Shepard's audio production. A Chorus Line's 2006 revival recording had the same problem, where it went from this wild, vital sign of the times to a squeaky clean, impersonally professional period piece.
