Nidaros or Niðarós was the medieval name of Trondheim in Norway, when it was the capital of the country's first Christian kings. It was named for its position at the mouth (Old Norse: óss) of the River Nid (today's Nidelva).

Although the capital was later moved to Oslo, Nidaros remained the centre of Norway's spiritual life until the Protestant Reformation. The archdiocese of Nidaros was separated from Lund in Sweden by the papal legate Nicholas Breakspeare in 1152 and the shrine of Saint Olaf in Nidaros Cathedral was Northern Europe's most important pilgrimage site during the Middle Ages. Archbishop Olav Engelbrektsson served as a leader of Norway in attempting to resist the Danish Reformation but was forced into exile by King Christian III in 1537. The archdiocese was abolished and replaced with a Lutheran superintendenture.

The Christianization of Norway was begun by Haakon the Good (d. 981), and carried on by Olaf Trygvesson (d. 1000) and Saint Olaf Haraldsson (d. 1030), two Vikings who had converted and been baptized at Andover in England and at Rouen in Normandy respectively.

Robert "Bob" Chilcott (born 9 April 1955) is a British choral composer, conductor, and singer, based in Oxford, England.

Born in Plymouth, Chilcott sang in the Choir of King's College, Cambridge, both as a boy and as a university student. He performed the Pie Jesu of Fauré's Requiem on the 1967 recording. In 1985 he joined the King's Singers, singing tenor for 12 years. He has been a composer since 1997.

Chilcott is well-known for his compositions for children’s choirs, including Can You Hear Me?, which he has conducted in the United States, Canada, Australia, Japan, Estonia, Latvia, Germany, and the Czech Republic. He is associated with the New Orleans Children’s Chorus and the Crescent City Festival in New Orleans, for which he wrote Jazz Mass, Happy Land, This Day, Be Simple Little Children, and for the 2009 festival, I Lift My Eyes.

Chilcott originally wrote This Day, a setting of five poems, for a 2006 choral festival in New Orleans which was cancelled after Hurricane Katrina. The work was eventually premiered on 25 June 2007 at St. Louis Cathedral in New Orleans, by 210 singers from around the United States.
