At the end of the concert, The Queen, helped by Gary Barlow, lit the final beacon - one of 4,000 around the world. As the flame lit (the very central one above), more fantastic fireworks went off around the palace.

Gary Barlow and Cheryl wowed the crowd with the song Need You Now. Gary himself had organised the whole concert and this was one of a number of appearances on stage for the X Factor judge.

One of the highlights of the night was Gary Barlow and Lord Andrew Lloyd Webber's song called 'Sing' performed by musicians from across the Commonwealth - the countries around the world which the Queen reigns over.

And here's Will again - this time with worldwide soul legend Stevie Wonder. They sang Stevie's version of 'Happy Birthday' to the Queen. We're wondering if they knew it wasn't actually the Queen's birthday this time!

Ed Sheeran entertained the 250,000 crowd with just his guitar for company. When they saw him walking on, the noise of their cheers drowned out the comedian Miranda Hart who was trying to introduce him!

Joining forces again were The Voice coaches and singing stars and Jessie J. Like most of the artists, they'd made a special effort to dress in red, white and blue. This wasn't the only superstar duet of the evening....

The concert was rounded off with a storming performance by Sir Paul McCartney, one of the two surviving Beatles - who were first famous in the 1960s. When the Queen started her reign in 1952, Sir Paul was just ten years old.

The Queen's eldest son, The Prince of Wales then gave a speech about her. He called her 'mummy'! He said it was sad that his father, The Duke of Edinburgh, couldn't be there too, because he was in hospital. But Charles got the crowd to cheer as loud as they could so the Duke could hear them from his bed!

The concert finished at around 10.30pm but Her Majesty stayed up even later to meet the stars backstage, including all the performers from across the Commonwealth. Kylie, who is Australian, had the job of introducing the Queen to Cheryl.

There were performers from every decade of the Queen's reign - including Kylie! The special stage outside the palace surrounded the statue of Queen Victoria - the only other British monarch to celebrate a Diamond Jubilee.

Yes, that really is Buckingham Palace - but a spectacular light show changed it to look more like an ordinary house. Up on the right, vintage 70s band Madness sang their famous song 'Our House' on the palace rooftop.
