Opera house (Scooby-Doo! Stage Fright)

Chicago's Opera House is a huge opera where the Talent Star had been set.

Scooby-Doo! Stage Fright
Since '70 the Phantom haunted the opera house because he hated Disco music but people thought he was part of the show until he destroyed the disco ball. The owner had to close but it was reopened for the Talent Star. Four more phantoms haunted the opera but Mystery Inc. captured them all.
