Anyone who has seen “Cats,” “Jesus Christ Superstar” or “Phantom of the Opera” will be surprised to learn that “House of Rock,” now at the Woodland Opera House, is also one of Andrew Lloyd Webber’s shows. Based on the 2003 film, written by Mike White, this is the story of Dewey Finn (Dallas Tringali), a failed wannabe rock star who earns extra cash to pay for his rent so he won’t be evicted by posing as a substitute teacher for a prestigious private school.
