I couldn’t verify the opener from the available public listing. The Magooby’s page for Josh Johnson confirms the show existed, but it does not name an opener in the accessible details.

What I could confirm

  • Magooby’s listed a Josh Johnson show page, including an event entry titled “JOSH JOHNSON IN 3D - Magooby’s Joke House”.
  • The search results available to me did not include the featured/opening comic’s name.

Best answer

The opener is not identifiable from the public information I could verify, so the safest answer is: unknown from the accessible listing.

Context

A few unrelated Magooby’s pages and posts surfaced, but none tied directly to Josh Johnson’s opener for that specific show.
