During a concert last week in Berlin, Sir Paul McCartney gave a moving tribute to the victims of a mass shooting at a gay nightclub in Orlando.

Forty-nine people died and dozens were injured when a lone gunman opened fire in the Pulse nightclub.

“We stand together with Orlando!” McCartney shouted in German while holding a rainbow flag.

McCartney draped the flag over his shoulder.

The 73-year-old went on to sing the 1965 Beatles classic Yesterday, which he wrote.

Other artists such as Queen + Adam Lambert have made similar tributes, while some singers – including Melissa Etheridge, Eli Lieb and Christina Aguilera – have written new music to help raise awareness and funds for the families of the victims.
