Query: QUEEN ROCKS MONTREAL

i can,t believe this production is 30 years old.the band and fredie mercury are so charged up. Play it loud .they will, they will ROCK YOU.it,s so great to see this production restored so well and the true performance of queen is captured forever.i wish other older bands could do this but most are lost forever.excellent use of technology.
