He said: “The early arrival of the groom and his best man was a break from royal tradition, but the princes wanted to mingle with the guests.”
Earlier that morning, William and Harry had also paid their respects at the Abbey with a salute to their fallen comrades as they passed London’s historic Cenotaph.
Footage in the documentary showed the brothers joking and laughing together as they arrived in their car, in what appears to be a stark contrast to their now strained relationship.
Meanwhile, Kate stunned on her big day as she wore a dress designed by Sarah Burton for Alexander McQueen while walking down the aisle with her proud father, Michael.

Billions of people watched Kate and William tie the knot
The Queen looked elegant as she wore a pale yellow dress and hat, as well as her signature handbag.
Many eyes were also on Kate’s sister Pippa’s flattering dress as she carried out her duties as bridesmaid.
Footage from the wedding also showed a huge sea of people holding small Union Jack flags as they gathered outside Buckingham Palace to see William and Kate’s famous balcony kiss.
Some of the guests who made appearances in the documentary were the florist, the former Archbishop of Canterbury and former Prime Minister David Cameron.

The Duke and Duchess of Cambridge also released a video of themselves enjoying time outdoors with their three children yesterday as part of the anniversary celebrations.
The 39-second clip, which was posted on their official Twitter account, showed the family at their Norfolk home, Anmer Hall, and on sand dunes at a nearby beach.
William and Kate thanked those who had sent “kind messages” to mark the milestone in a tweet alongside the video.
The personal message, signed W&C, said: “Thank you to everyone for the kind messages on our wedding anniversary.
The Duke and Duchess of Cambridge have been married since 2011
“We are enormously grateful for the 10 years of support we have received in our lives as a family.”
The video offered a rare glimpse into the Cambridges’ family life.
At one point, it showed the couple sharing a joke with their youngest son, Prince Louis, while at another the whole family are seen toasting marshmallows over a bonfire.
The family looked happy in each other’s company, with both the duke and duchess shown chasing, playing and holding hands with their children.

Earlier this month, Harry joined his brother and other members of the Royal Family to bid farewell to Prince Philip for his funeral.
Harry had returned to the UK for the first time since stepping down as a senior royal to live with wife Meghan Markle and son Archie in California last year.
He is reported to have held brief meetings with his father Prince Charles and brother William, but he then flew back to the US.
Tensions were said to be high after his explosive Oprah interview a month earlier, where Harry took aim at his family.
He said he felt trapped in the Royal Family and shared his “compassion” for his brother and father Prince Charles being unable to leave their roles.
He also said he was on a “different path” to William as there was “space” between them.
Harry had the important role of being best man at his brother’s wedding
Harry said: “My father and my brother, they are trapped. They don’t get to leave. And I have huge compassion for that.”
William was the first royal who spoke out publicly as he told reporters a few days after the interview was aired that he had not spoken to his brother.
The Queen also issued a statement saying “while some recollections may vary”, the issues would be taken “very seriously”, but dealt with privately as a family.
Harry could be returning to the UK again in July as he will reportedly stand with William at the unveiling of a statue for Princess Diana, at Kensington Palace, on what would have been her 60th birthday.
