Beyond the misery and melancholy for which the French songbird is best known lies some lighter lyrical realism. Piaf quotes clothes sellers' cries from the streets of Paris in the 1936 recording "Chants d'habits," and she offers a glimpse into the café culture in which she flourished in the lilting "L'homme au piano.” Meanwhile, back in the blues, "Heaven Have Mercy” provides a rare English-language rummage through Piaf's bottomless bureau of betrayal.
