Some explanation to every non french people...
The guy is french. He has been there for... more than 40 years... (he is 67)
The name Hallyday has been chosen because in the 60s, it was nice to have an english name, but in the other hand no one spoke english (well actually that part is still true). In fact his father was belgium.
A part of the population thinks he singing god and every time he performs a show, the concert is booked up.
Another part (like me) thinks that he does not sing but shout in the mike.
There are lots of jokes that describes him as nice but stupid.
Now, i wont play the game !
