Stade de france if I got the right place,is a pretty big venue if they're using the whole stadium. The one I'm thinking of is the national stadium that seats about 80,000. I remember it from when several years ago MF announced 2 shows there as a part of a tour and the first show sold out within 2 hours and the next one, not long after.
EDIT: I just saw the instagram page and that looks like the place. I wonder if the place will sell out?
Double edit: I was trying to find out more info on the show. So I guess it's a show that mainly focuses on hits from the eighties and one video I looked at, I believe this singer mentioned JPVA at the 1:15 mark, or am I hearing things? He was probably just referring to the fact he's not 20.
