It was a night on which the Queen took centre stage, as thousands gathered to celebrate her 60 years on the throne.
But there was also much interest in the family members, friends and dignitaries who joined the monarch for the Jubilee concert on Monday night.
Guests from across the globe, young and old, sat in the Royal Box at the Buckingham Palace event to watch stars including Stevie Wonder, Sir Elton John and Kylie Minogue perform.

Joining the Queen on the front row were Prince Charles, Princess Anne and Prince Andrew, along with the Archbishop of Canterbury and his son Pip.
A notable absence from the line up was obviously Prince Philip, who was in hospital recovering from a bladder infection which left him feeling below par after hours standing in the cold and rain during the Thames River Pageant on Sunday.
Standing just behind the Queen's row were several other members of the Royal Family, including Prince William and Kate Middleton, Prince Harry, Princesses Beatrice and Eugenie, Prince Edward and the Countess of Wessex.
Royal couple Mike Tindall and Zara Phillips sat in the third row, alongside Zara's brother Peter, his wife Autumn, and Viscount and Viscountess Linley.
Politicians sat in the fourth row with David Cameron and his wife Samantha sitting alongside Nick Clegg.
Mr Cameron sat next to the Governor General of Canada, David Johnston and his wife Sharon.

JUBILEE CONCERT BY NUMBERS
Others in the Royal Box included chef Heston Blumenthal and his partner Suzanne Pirret.
The world-renowned British chef had conjured up a remarkable five-course menu for 12,000 lucky guests who secured free tickets for the concert.
classic hampers featured traditional British dishes such as coronation chicken and Eton mess with a Blumenthal twist.
Former Prime Minister Sir John Major and his wife Norma were at the concert, sitting next to his Tory colleague Lord Coe.
Lord Coe, who is leading London's preparations for the Olympics this summer, attended with his wife Carole Annett.
BBC Director-General Mark Thompson also watched the concert.
Some 12,000 contest winners watched the show from an enclosed area, while a huge crowd stretched down the Mall, the wide boulevard leading up to the palace.
The lineup featured a full hand of knights - McCartney, John, Cliff Richard and Tom Jones, all 'Sirs' - along with Dame Shirley Bassey and younger artists including JLS and Kylie Minogue.
The show opened in a blaze of sound and colour, as a scarlet-clad military band joined Robbie Williams onstage for his hit 'Let Me Entertain You.' Black Eyed Peas star Will.i.am performed 'I Gotta Feeling' with songstress Jessie J.
In true something-for-everyone mode, performances ranged from pianist Lang Lang playing Gershwin to American soprano Renee Fleming to 64-year-old Grace Jones hula-hooping her way through 'Slave to the Rhythm.'
Performers from around the world sang a special jubilee song written by Andrew Lloyd Webber and Take That`s Gary Barlow.
It was the veteran entertainers who went down best. The crowd roared along to Cliff Richard's "Congratulations," and cheered Bassey singing - fittingly - 'Diamonds are Forever.'
Prince Harry could be seen singing along - 'Why, why why?' - as Tom Jones belted out 'Delilah,' while Prince William and his wife Catherine joined in on John's 'Crocodile Rock.'
Ska band Madness performed 80s hit 'Our House' on the palace roof, changing the lyrics to 'Our house, in the middle of one's street.'
The queen may not like to rock'n'roll but she has plenty of fans among rock's elite.
Before the show, Elton John paid tribute to the monarch's constancy.
'She's not trendy, she doesn't follow any fads,' John told the BBC. 'She's stoic, she's brilliant, she's wise, she's funny, and we're all really happy to be here.'
McCartney closed the concert playing 'Ob-La-Di, Ob-La-Da' on a Union Jack guitar before the queen took the stage with her family.
