Don't know what the Nouveau Casino looks like but I'll be there; got my ticket yesterday. Sure a venue you don't appreciate can spoil your fun (le Zénith, Paris, is a place I didn't like when I saw SY there; same things for l'Arapaho - don't know if it still exists, with its pillar, and le Trabendo).
The finest place I saw a concert at was le Vauban, in Brest. A small place with a stage you could climb on effortlessly.
Well I hope the 380 won't feel toooooo proud to be there. SY should have stayed a couple of more nights to downsize the buzz.
