Hey Ponine, that's what I had.
Since there's no question on the table right now, I'll toss another music question out there:
There's a piece of music on a Disney attraction that was intended by the composer to play through the entire attraction (in one form or another, with the chord progression unbroken). Once the attraction was completed, however, the theme was interrupted by a short twisted version of a piece of music from a famous opera.
Name the attraction and the composer. For bonus points, name the music used in the 'interruption' and its source.
Big Hint:
