Johnny Mercer: The Dream's on Me

I have often wondered, through the years, why no one had produced a bio of this talented man. Then I found this and ordered the DVD. I was not impressed at all. It was disjointed and painful to watch. I learned next to nothing about the man himself. His personal life is virtually non-existent. He seems to appear to be about 50 years old throughout the movie. It was more of a paean than a biography. I wish it had had a more chronological aspect. Did Julie Andrews appear for more than 15 seconds? What I found particularly confusing was the dates of composition versus the dates of performance. I hope someone in the near future comes up with a better effort.
