Did you see them all? I think it's a worthy distinction because the performance is unmatched by the OBCR, especially say for a star vehicle like Woman of the Year, or something like Steel Pier which very few people saw.
I'll rank and put an asterisk next to the ones I only know via recording.
Kiss of the Spiderwoman
The Scottsboro Boys
The Happy Time*
Woman of the Year*
Flora the Red Menace*
70 Girls 70* – sadly have not ever seen or listened to the recording. Shame.
I also LOVE the songs they wrote for New York, New York and Funny Lady
