TOD:
Johnny Mercer on stage. Too many songs on Saratoga sound truncated, would love some of the songs from The Good Companions, plus Foxy, St. Louis Woman, etc.
Hugh Martin: Make a Wish has some great stuff. Love High Spirits, Best Foot Forward, even Love from Judy. Of course, he wrote great stuff for the movies, too. (Doubt anyone would know it.)
Flaherty and Ahrens has built a strong body of work.
There is a series out there that looks at Broadway year by year, but that doesn't work for me as well as a look at various seasons would.
and I'll second the Carolyn Leigh nomination.
