Keith Urban performed a touching tribute to the victims of the Orlando nightclub mass shooting while in Florida on Friday (17Jun16). The 48-year-old rocker sang a cover of U2's One, and told the crowd at the MIDFLORIDA Credit Union Amphitheatre in Tampa, "Although I didn’t know anybody in that horrific incident, I did, because they’re just guys and girls, brothers and sisters. They had dreams, hopes, plans, just like every one of us. Orlando strong!" In what has been called America's worst mass shooting, 49 people were killed and more than 50 injured in the attack on gay nightclub Pulse on 12 June (16).
