Prince George's christening ceremony included two hymns, two lessons and two anthems, according to Kensington Palace.
Prince Harry read him a lesson form John 15:1-5, and his aunt Pippa Middleton read Luke 18:15-17.
The music started with a processional, Bach's "Fantasia in G," played on organ.
The Choir of Her Majesty's Chapel Royal, made up of six men and 10 boys, sang the anthem "Blessed Jesu! Here we Stand," which was written for the baptism of baby George's father, Prince William, in 1982.
The second anthem was "The Lord Bless You and Keep You" by John Rutter.
The newest royal also heard the hymns "Breathe on Me, Breathe on God" and "Be Thou My Vision" before the organ played the recessional, which was C.W. Widor's Toccata from Symphony No. 5.
