Celebrating the 1812 Overture is a "mini episode", but counts as a full on episode, making the episode it's paired up with, Closer to Mars, a bit longer. This episode is the 16th episode of Season 31 on Disney and the 30th on Nickelodeon. Phineas and Ferb gather their friends and celebrate the 1812 Overture with a party and form their own orchestra and play the famous part of the overture. Matt Wilhelm makes a guest voice actor for the host of the party, Amazing Adam.
