"Sto lat" (One Hundred Years) is a traditional Polish song that is sung to express good wishes to a person. The song's author and exact origin are unattributed. The song is sung both at informal gatherings (such as birthdays or namesdays) or at formal events, such as weddings; it has been played, for example, at the recent presidential inauguration of Lech Kaczyński and during visits by Pope John Paul II.* At state events it is not unusual to hear it performed by an orchestra or a military band.
The song serves the equivalent function of "Happy Birthday To You" or "For He's a Jolly Good Fellow". Although a secular song, its message is similar to that of the Ukrainian song "Mnohaya lita" (Многая літа, Many Years), a version of a Byzantine liturgical hymn. *
