Now that the choir has ten members, it's time to get serious about entering the Kanto boys choir competition! The boys find out that last year's national winners are performing at a festival, so they go to check them out. Then they run into Maiden's dad!
If you're going to play, you have to do
 it right or else it's rude to the music.
إن كنتم ستعزفون، فيجب أن تفعلوها كما يجب
وإلّا ستكون فظاظة للموسيقى
Wenn man das nicht ordentlich macht,
beleidigt man die Musik!
Siete voi quelli scortesi verso la musica!
Se volete suonare, almeno fatelo bene!
Коль вышли на сцену — 
так уважайте музыку, играйте правильно.
