The prospective purchaser of "Stephen Sondheim: A Life" is likely to be misled by this remark: "people seem to be missing the point--this isn't a critical biography, but a personal one". In fact, until she undertook to write it, the author of this book had no personal or professional relationship with its subject whatsoever. It is a thing anyone sufficiently motivated could throw together, and I can't in good conscience recommend it. I can and do recommend Craig Zadan's "Sondheim & Company", and for those interested in musical theatre in general, Richard Rodgers's "Musical Stages" and Alan Jay Lerner's "The Street Where I Live".
