The world-renowned Vienna Boys Choir will perform in the First United Methodist Church sanctuary. Since 1926, the Vienna Boys Choir has undertaken around 1000 tours in 97 different countries; in that time, the boys have sung more than 27,000 concerts. There are currently 100 choristers between the ages of nine and fourteen, divided into four touring choirs. They give around 300 concerts each year, attended by almost half a million spectators around the world. Together with the Vienna Philharmonic Orchestra and the Vienna State Opera Chorus, the boys provide the music for the Sunday Mass in the Imperial Chapel, as they have done since 1498.
