Probably through not paying attention, I always thought Léo Ferré had (a) a funny name for his grandmother (“Pépée,” a feminine form of “pépé” or “little old guy”?). That made sense because, as far as I could tell, Léo had (b) an odd granny, whose hands were like tennis rackets and whose ears stuck out like Serge Gainsbourg's but were never tamed with bits of scotch tape. But now, looking for something else, I stumble across this and all my questions are answered.
