If you love musical theatre works from 1866 thru 1960 - this is the book for you. Exhaustively researched. However, if you never ended the affair, and love Sondheim, Coleman, Fosse, Kander & Ebb, Champion, Lapine, Tune, Bennett, McNally, Herman, Hamlisch, Patinkin, Peters and LuPone - well, this probably ISN'T the book for you. The first 100 years are wonderfully detailed. Six paragraphs on "Show Boat" alone. Great. However, the author seems to have lost interest in his subject matter. The greatest shows of the past forty years are lucky to get a single paragraph. The last sections of the book feel passionless and rushed, the reportage at best perfunctory. It's too bad that someone like Ethan Mordan couldn't revisit and revise these decades. $ - wow! Listen, buy a used copy of the first edition (it goes up to 1978), than look for some of Mordan's books or Ken Mendelbaum's "Not Since Carrie."
