Rock band Queen and Paddington Bear kick off Queen Elizabeth’s Platinum Jubilee concert

Prince Charles and his son Prince William honoured the past and looked to the future on Saturday as they paid tribute to Queen Elizabeth at a star-studded concert outside Buckingham Palace celebrating the monarch’s 70 years on the throne.

Rock band Queen, Duran Duran, Alicia Keys, Diana Ross and others performed in front of some 22,000 people gathered on the Mall outside Buckingham Palace for the open-air “Party at the Palace,” which rounded up the third day of a four-day holiday weekend dedicated to celebrating the queen’s Platinum Jubilee.

The queen may have had to miss the concert, but she brought the house down when she appeared in a surprise video recorded with another British national treasure: Paddington Bear.

The 96-year-old monarch said she shared Paddington’s love of marmalade sandwiches in a surprise video, delighting thousands who gathered outside Buckingham Palace for the third day of a Platinum Jubilee extravaganza marking her 70 years on the throne.

Charles opened his short speech by addressing the queen as “Your Majesty, mummy,” then paid tribute to her “lifetime of selfless service.”

The queen’s eldest son and heir recalled the ever-growing list of world leaders Elizabeth has met and the endless stacks of state papers she has reviewed during a reign that has now stretched from the early days of the Cold War to the information age. But he also highlighted his mother’s role as a symbol of stability, unifying the UK and the Commonwealth as they negotiated this rapidly changing world.

“You have met us and talked with us. You laugh and cry with us and, most importantly, you have been there for us, for these 70 years,” Charles said as scenes from the queen’s life were projected on the palace walls.
