Due to the longevity of the Indianapolis 500, numerous traditions surrounding the race have developed over the years. Traditions include procedures for the running of the race, scheduling, and pre-race and post-race festivities. For many fans, these traditions are an important aspect of the race, and they have often reacted quite negatively when the traditions are changed or broken.
As part of the Memorial Day holiday weekend, the pre-race ceremonies of the Indianapolis 500 feature several patriotic songs. Like most other sporting events, the national anthem is performed before the race by a notable vocalist. The most noteworthy and most popular traditions are the annual singing of the chorus of "Back Home Again in Indiana," and the victory lane bottle of milk.
