Hello Studata Girl! Thanks for registering
I've attended the show once, so I'll try to answer you with what I know and let others add more info.
1) September 5
2) If you live in Montreal, yes!
3) You'll expect the same quality material as the 10 displays we saw this year, that is the best fireworks in the world
4) I guess that's La Ronde
5) La Ronde? I don't know if there will be music this year. I think, there was, but you'll only be able to hear it from La Ronde
6) They use the unnexploded products from this summer's contestants. I don't know if they only use those, though.
