Yes, that, perhaps with too much subtlety, was my point. The movie had nothing much to recommend it so just get a Piaf CD and listen to that.
Though all of the singing wasn't Edith Piaf, not everything existed in recorded form that could be used in the movie. One of the NPR shows had an interview with Jil Aigrot the French woman who four songs in the movie. She has a successful career in France doing Piaf tribute shows (
here's some of it on YouTube).
And it certainly isn't her fault that it is a timeworn story. But that doesn't make it any more interesting to see it for the fourth or fifth time in a couple years.
