The Queen had to re-record last year's Christmas message after she was interrupted by a chirping bird in the gardens of Buckingham Palace.
Her Majesty, known affectionately as 'One Take Windsor' for her ability to get things right the first time, was told to redo the whole speech 'from the top' by member of the production team.
The Queen's response is revealed as part of the new ITV documentary Queen of the World.
In the exchange, the crew member tells the queen to "redo it from the top" when the bird starts cheeping.
The Queen replied: "From the top of the second page?"
The crew member says: "From the very start."
The Queen then says: "You want the whole thing again?"
She chuckles as she is told "if possible" by the member of the TV crew.
In further scenes from the hotly anticipated documentary, Meghan Markle revealed some of the secrets of her wedding dress.
She details how her 'something blue' for the wedding was stitched into the fabric of the dress.
On seeing her wedding dress again she said: ""My goodness! It's amazing, isn't it?"
"Wow, very pretty. Beautiful. Somewhere in here, there’s a piece of…did you see it? The piece of blue fabric that's stitched inside?
"It was my 'something blue'. It's fabric from the dress that I wore on our first date" she reveals."
The Duchess of Sussex also tells the story behind her decision to have the distinctive flora of each 53 Commonwealth countries incorporated into the design of her veil, revealing it was a "surprise" for Prince Harry.
She said: "It was important for me, especially now being a part of the royal family, to have all 53 of the Commonwealth countries incorporated, and I knew that it would be a fun surprise as well for my now husband, who didn't know, and he was really over the moon to find out that I would make this choice for our day together."
