Prince Charles gave the couple advice on the wedding music.

The soon-to-be wedded couple sought musical advice from Prince Charles for their big day.

This was amongst all the nuggets of information released by the Royal Household about the Order of Service for Meghan Markle and Prince Harry's wedding day.

Prince Charles advised the couple on orchestral music that will play in St George's Chapel before the service begins, including a piece called Prelude and Fugue in G Major BWV 541 by Johann Sebastian Bach.

Prince Charles is walking Meghan down the aisle, and helping the couple with their music choices.

The order of service indicated that people wearing hearing aids in the chapel have been told to put the setting to T, and photos, videos, or sound recordingis not permitted inside the chapel.

The service is being led by The Right Reverend David Conner KCVO, Dean of Windsor, and the marriage is being solemnized by The Most Reverend and Right Honourable Justin Welby, Archbishop of Canterbury.

The Dean of Windsor will introduce the couple by their given names, Henry Charles Albert David and Rachel Meghan, however from then on they will be referred to as Harry and Meghan.

In the declarations, the Archbishop of Canterbury will ask "Harry, do you take Meghan to be your wife?".  This is unlike Prince William and Kate, who continued to use their full names throughout their wedding ceremony.

The couple will be using the Common Worship (2000), and will say 'I will', instead of 'I do'.

Furthermore, the Church of England, of which the Queen is the supreme governor, wrote a special prayer for the couple: God of love, send your blessing upon Harry and Meghan, and all who are joined in marriage, that, rejoicing in your will and continuing under your protection, they may both live and grow in your love all their days, through Jesus Christ our Lord. Amen.
