Thanks to Martin Cowan:
“Dylan Daily readers who are curious about the work of film director Olivier Dahan (evidently it was his request for a suitable song for his latest movie that inspired the feverish song writing that resulted in "Together Through Life") had the opportunity to see his earlier film about Edith Piaf, shown on BBC4 yesterday.”
(Though I like Edith Piaf’s music, and love Paris, the film wasn’t my tasse de the: trop crasse, a mon avis - GS)
