DR JohnG, I enjoyed the two Blue Moon reviews. Lorenz Hart remains my favorite lyricist, and the film sounds very interesting. I'm sure this excellent book was very helpful to the screenwriter, since it really covers complicated relationship of Rodgers & Hart in the late 1930s when Rodgers became more frustrated over Hart's personal issues. The interviews in it make it clear that 20-30 years after Hart's death, Rodgers still had a hard time coping with Harft.
For the record, one of the two authors, Jan Clayton, was the original star of the Rodgers & Hammerstein Carousel.
