Les cinglés du music-hall was a radio program every saturday by Jean-Christophe Averty who shared during 28 years (until 2006) his immense knowledge of the field with an amazing energy and completely orginal delivery. Here on daily motion about la môme moineau (1926 in New York, the phenomenal success of Night in Paris). A vos cassetttes! Apparently he gave all his rights to l'INA in 2012. What are they doing with all of this? Not much that I can see on line now but maybe I did not look hard and long enough...
