Most of those are new to me. I just watched Good News recently, review is up in the "Respond" thread. My rankings of the ones I've seen:
42nd Street
Le Million
The Young Girls of Rochefort
A Mighty Wind
Hallelujah
Monterey Pop
Umbrellas of Cherbourg
Good News
42nd Street is almost a "teal" film (i.e., top 100-worthy) for me.
