This is a concise, comprehensive publication, covering absolutely everything regarding the play, "My Fair Lady" - includes the entire liberetto (That is to say, lyrics and lines), and also contains cast list from the 1964 film and photo stills from the said film.
Stage directions are accurate and give a lot of guidance, but still allow for a lot of dramatic license.

In short, I highly reccomend this book to anyone who wishes to have a script for "My Fair Lady", especially those looking to direct a production.

The piano part is as complex as it needs to be, and important orchestral grace notes are also provided. At no point is the accompaniment dumbed down in any way, and it faithfully captures all the sophisticated rhythms and harmonies of the original production.

In short, I can recommend this book most highly.
