not a singer,an insider close to koffi during the most of quartier latin existence,he was a man of trust who could help out on different matters(setup at rehearsals,cleaning,taking care of koffi's safety when he eats or drinks and has to move away,to make sure nobody touches it for example to put poison which is why koffi in his tribute is saying that he was somebody you had to face as one of the last "barriers" to ever approach him to try to cause him harm
that was his second stroke in a couple of month/years and it killed him
