Incidentally, Benin's (or Dahomey as it then was) former President, Emile Zinsou is evidently still alive. Having been sentenced to death in absentia 32 years ago he's probably stopped looking over his shoulder, but at 88, his days may be numbered. Not a lot of information, though.
Emile Zinsou, now 96, was hospitalised in June and the outlook doesn't look particularly promising... (article is in French)
Never heard of either.
But I can see how someone might have said to Emile, "Are you Dahomey that is President of Benin?"
