And now, before we go to bed, let us sing the school song! Everyone pick their favorite tune and off we go!. -- Albus Dumbledore (PS7) The Hogwarts School Song is a short anthem praising Hogwarts which is sung by the entire student body and staff on special occasions. Dumbledore directed the school song at the end of the start-of-term feast when he felt in a particularly festive mood. The last time the song was known to be sung was during the feast on September 1, 1991, when Harry Potter came to Hogwarts. Dumbledore directed the song with his wand.
