Wedding March is a song written by Felix Mendelssohn in 1842. It was written for Shakespeare's A Midsummer Night's Dream. It has since been used in several weddings even to this day.
Because the song is public domain, it has been used in several video games.
Libble Rabble (ARC)
Creative Music System (DOS)
Haunted Castle (ARC)
The song is played during the introduction sequence and is rendered on the cabinet's Konami SCC chip.
King's Quest II: Romancing the Throne (DOS)
Dr. Jekyll and Mr. Hyde (NES)
The song plays during the game's ending sequence.
During the ending, we see the good doctor and Ms. Millicent meet at the church. Walk toward each other very slowly, and then go inside the church. The text END is then displayed. If the player beat Letule as Mr. Hyde, then the song will be interrupted by an alternate ending of a silhouette of Hyde.
Yuuyuu Jinsei (PCE)
The song plays during the marriage cutscene.
The album Kinoko Kunimoto Takeaki History Vol.5: Katoken titles the song Kekkonshiki (結婚式 = Wedding).
There seems to be an error where one of the instruments is a 16th note out of sync with the rest of the instrumentation.
