During the opening and closing credits, the music is from W.A. Mozart's Serenade # 13 for strings in G Major, K. 525, better known as "Eine Kleine Nachtmusik". In addition, the music during the scene where Michael is helping Granny out of her wet clothes and then again during several subsequent scenes involving Granny is a re-write of a portion of the 1st movement from Beethoven's Piano Concerto # 5, also known as the "Emperor" Concerto. It is uncertain why this went unmentioned in the movie's credits, as if James Newton Howard was the original composer of this music.
