I have almost finished (With like 20 pages left to read) "The Other Side of the Rainbow with Judy Garland on the Dawn Patrol" by Mel Torme. Published by Morrow and Company, Inc. in New York 1970. This book primarily deals with the period of time Judy was shooting "The Judy Garland Show" for CBS. The book also goes into some details of Mel's private life at the time as well.
The title has to do with the early morning phone calls Judy would make to some of the staff concerning her worries about the show, her talent, her abilities and how she was being perceived on the show. The majority of the phone calls where like 2 to 4 a.m. and grew into the nickname "The Dawn Patrol" for those that got the phonecalls, soothed Judy's nerves and made the show go on.
I want to say some of what others have said about the book:
"Mel had the guts to relive the story our hearts were too full to recall"--Mickey Rooney
"A Vivid and highly sophisicated glimpse of the unfathambale Judy- the driven, the talented, the tormentor, and the tormented". Gerald Frank
