Also of note during this sequence was the second appearance from Michael Sun Lee as Stephanie’s aces friend Harry Takayama.
He popped into the finale as a “tryout” to officiate D.J., Stephanie and Kimmy’s weddings, and actually SANG PART OF “YANKEE DOODLE DANDY” in an immediate callback joke at the end of the montage.
Derek, of course, played Yankee Doodle in the America the Beautiful play while decked out in his reddest, whitest and bluest.
Of all the final-season cameos, arguably the most mind-blowing was the long-wanted cameo from Blake McIver Ewing as Stephanie’s childhood friend Derek Boyd, who was responsible for another one of Full House’s most memorable musical moments.
